Relevanssi replaces the default search with a partial-match search that sorts results by relevance. It also indexes comments and shortcode content.

== Description ==

Relevanssi replaces the standard WordPress search with a better search engine, with lots of features
and configurable options. You'll get better results, better presentation of results - your users
will thank you.

This is the free version of Relevanssi. There's also Relevanssi Premium, which has added features.
For more information about Premium, see [Relevanssi.com](http://www.relevanssi.com/).

= Key features =
* Search results sorted in the order of relevance, not by date.
* Fuzzy matching: match partial words, if complete words don't match.
* Find documents matching either just one search term (OR query) or require all words to appear (AND query).
* Search for phrases with quotes, for example "search phrase".
* Create custom excerpts that show where the hit was made, with the search terms highlighted.
* Highlight search terms in the documents when user clicks through search results.
* Search comments, tags, categories and custom fields.

= Advanced features =
* Adjust the weighting for titles, tags and comments.
* Log queries, show most popular queries and recent queries with no hits.
* Restrict searches to categories and tags using a hidden variable or plugin settings.
* Index custom post types and custom taxonomies.
* Index the contents of shortcodes.
* Google-style "Did you mean?" suggestions based on successful user searches.
* Automatic support for [WPML multi-language plugin](http://wpml.org/).
* Automatic support for [s2member membership plugin](http://www.s2member.com/).
* Advanced filtering to help hacking the search results the way you want.
* Search result throttling to improve performance on large databases.
* Disable indexing of post content and post titles with a simple filter hook.

Relevanssi is available in two versions, regular and Premium. Regular Relevanssi is and will remain
free to download and use. Relevanssi Premium comes with a cost, but will get all the new features.
Standard Relevanssi will be updated to fix bugs, but new features will mostly appear in Premium.
Also, support for standard Relevanssi depends very much on my mood and available time. Premium
pricing includes support.

= Premium features (only in Relevanssi Premium) =
* Improved spelling correction in "Did you mean?" suggestions.
* Multisite support.
* Search and index user profiles.
* Search and index taxonomy term pages (categories, tags, custom taxonomies).
* Search and index arbitrary columns in wp_posts MySQL table.
* Assign weights to any post types and taxonomies.
* Assign extra weight to new posts.
* Let the user choose between AND and OR searches, use + and - operator (AND and NOT).
* Highlighting search terms for visitors from external search engines.
* Export and import settings.

= Relevanssi in Facebook =
You can find [Relevanssi in Facebook](http://www.facebook.com/relevanssi).
Become a fan to follow the development of the plugin, I'll post updates on bugs, new features and
new versions to the Facebook page.

= Other search plugins =
Relevanssi owes a lot to [wpSearch](http://wordpress.org/extend/plugins/wpsearch/) by Kenny
Katzgrau. Relevanssi was built to replace wpSearch, when it started to fail.

Search Unleashed is a popular search plugin, but it hasn't been updated since 2010. Relevanssi
is in active development and does what Search Unleashed does.



== Installation ==

1. Extract all files from the ZIP file, and then upload the plugin's folder to /wp-content/plugins/.
1. If your blog is in English, skip to the next step. If your blog is in other language, rename the file *stopwords* in the plugin directory as something else or remove it. If there is *stopwords.yourlanguage*, rename it to *stopwords*.
1. Activate the plugin through the 'Plugins' menu in WordPress.
1. Go to the plugin settings and build the index following the instructions there.

To update your installation, simply overwrite the old files with the new, activate the new
version and if the new version has changes in the indexing, rebuild the index.

= Note on updates =
If it seems the plugin doesn't work after an update, the first thing to try is deactivating and
reactivating the plugin. If there are changes in the database structure, those changes do not happen
without a deactivation, for some reason.

= Changes to templates =
None necessary! Relevanssi uses the standard search form and doesn't usually need any changes in
the search results template.

= How to index =
Check the options to make sure they're to your liking, then click "Save indexing options and
build the index". If everything's fine, you'll see the Relevanssi options screen again with a 
message "Indexing successful!"

If something fails, usually the result is a blank screen. The most common problem is a timeout:
server ran out of time while indexing. The solution to that is simple: just return to Relevanssi
screen (do not just try to reload the blank page) and click "Continue indexing". Indexing will
continue. Most databases will get indexed in just few clicks of "Continue indexing". You can
follow the process in the "State of the Index": if the amount of documents is growing, the 
indexing is moving along.

If the indexing gets stuck, something's wrong. I've had trouble with some plugins, for example
Flowplayer video player stopped indexing. I had to disable the plugin, index and then activate
the plugin again. Try disabling plugins, especially those that use shortcodes, to see if that
helps. Relevanssi shows the highest post ID in the index - start troubleshooting from the post
or page with the next highest ID. Server error logs may be useful, too.

= Using custom search results =
If you want to use the custom search results, make sure your search results template uses `the_excerpt()`
to display the entries, because the plugin creates the custom snippet by replacing the post excerpt.

If you're using a plugin that affects excerpts (like Advanced Excerpt), you may run into some
problems. For those cases, I've included the function `relevanssi_the_excerpt()`, which you can
use instead of `the_excerpt()`. It prints out the excerpt, but doesn't apply `wp_trim_excerpt()`
filters (it does apply `the_content()`, `the_excerpt()`, and `get_the_excerpt()` filters).

To avoid trouble, use the function like this:

`<?php if (function_exists('relevanssi_the_excerpt')) { relevanssi_the_excerpt(); }; ?>`

See Frequently Asked Questions for more instructions on what you can do with
Relevanssi.

= The advanced hacker option =
If you're doing something unusual with your search and Relevanssi doesn't work, try
using `relevanssi_do_query()`. See [Knowledge Base](http://www.relevanssi.com/knowledge-base/relevanssi_do_query/).

= Uninstalling =
To uninstall the plugin remove the plugin using the normal WordPress plugin management tools
(from the Plugins page, first Deactivate, then Delete). If you remove the plugin files manually,
the database tables and options will remain.

= Combining with other plugins =
Relevanssi doesn't work with plugins that rely on standard WP search. Those plugins want to
access the MySQL queries, for example. That won't do with Relevanssi. [Search Light](http://wordpress.org/extend/plugins/search-light/),
for example, won't work with Relevanssi.

[ThreeWP Ajax Search](http://wordpress.org/extend/plugins/threewp-ajax-search/) is
an AJAX instant search plugin that works with Relevanssi.

Some plugins cause problems when indexing documents. These are generally plugins that use shortcodes
to do something somewhat complicated. One such plugin is [MapPress Easy Google Maps](http://wordpress.org/extend/plugins/mappress-google-maps-for-wordpress/).
When indexing, you'll get a white screen. To fix the problem, disable either the offending plugin 
or shortcode expansion in Relevanssi while indexing. After indexing, you can activate the plugin
again.

== Frequently Asked Questions ==

= Knowledge Base =
You can find solutions and answers at the [Relevanssi Knowledge Base](http://www.relevanssi.com/category/knowledge-base/).

= Relevanssi doesn't work =
If you the results don't change after installing and activating Relevanssi, the most likely 
reason is that you have a call to `query_posts()` on your search results template. This confuses
Relevanssi. Try removing the query_posts call and see what happens.

= Where are the user search logs? =
See the top of the admin menu. There's 'User searches'. There. If the logs are empty, please note
showing the results needs at least MySQL 5.

= Displaying the number of search results found =

The typical solution to showing the number of search results found does not work with Relevanssi.
However, there's a solution that's much easier: the number of search results is stored in a
variable within $wp_query. Just add the following code to your search results template:

`<?php echo 'Relevanssi found ' . $wp_query->found_posts . ' hits'; ?>`

= Advanced search result filtering =

If you want to add extra filters to the search results, you can add them using a hook.
Relevanssi searches for results in the _relevanssi table, where terms and post_ids are listed.
The various filtering methods work by listing either allowed or forbidden post ids in the
query WHERE clause. Using the `relevanssi_where` hook you can add your own restrictions to
the WHERE clause.

These restrictions must be in the general format of 
` AND doc IN (' . {a list of post ids, which could be a subquery} . ')`

For more details, see where the filter is applied in the `relevanssi_search()` function. This
is stricly an advanced hacker option for those people who're used to using filters and MySQL
WHERE clauses and it is possible to break the search results completely by doing something wrong
here.

There's another filter hook, `relevanssi_hits_filter`, which lets you modify the hits directly.
The filter passes an array, where index 0 gives the list of hits in the form of an array of 
post objects and index 1 has the search query as a string. The filter expects you to return an
array containing the array of post objects in index 0 (`return array($your_processed_hit_array)`).

= Direct access to query engine =
Relevanssi can't be used in any situation, because it checks the presence of search with
the `is_search()` function. This causes some unfortunate limitations and reduces the general usability
of the plugin.

You can now access the query engine directly. There's a new function `relevanssi_do_query()`,
which can be used to do search queries just about anywhere. The function takes a WP_Query object
as a parameter, so you need to store all the search parameters in the object (for example, put the
search terms in `$your_query_object->query_vars['s']`). Then just pass the WP_Query object to
Relevanssi with `relevanssi_do_query($your_wp_query_object);`.

Relevanssi will process the query and insert the found posts as `$your_query_object->posts`. The
query object is passed as reference and modified directly, so there's no return value. The posts
array will contain all results that are found.

= Sorting search results =
If you want something else than relevancy ranking, you can use orderby and order parameters. Orderby
accepts $post variable attributes and order can be "asc" or "desc". The most relevant attributes
here are most likely "post_date" and "comment_count".

If you want to give your users the ability to sort search results by date, you can just add a link
to http://www.yourblogdomain.com/?s=search-term&orderby=post_date&order=desc to your search result
page.

Order by relevance is either orderby=relevance or no orderby parameter at all.

= Filtering results by date =
You can specify date limits on searches with `by_date` search parameter. You can use it your
search result page like this: http://www.yourblogdomain.com/?s=search-term&by_date=1d to offer
your visitor the ability to restrict their search to certain time limit (see
[RAPLIQ](http://www.rapliq.org/) for a working example).

The date range is always back from the current date and time. Possible units are hour (h), day (d),
week (w), month (m) and year (y). So, to see only posts from past week, you could use by_date=7d
or by_date=1w.

Using wrong letters for units or impossible date ranges will lead to either defaulting to date
or no results at all, depending on case.

Thanks to Charles St-Pierre for the idea.

= Caching =
Relevanssi has an included cache feature that'll store search results and
post excerpts in the database for reuse. It's something of an experimental 
feature right now, but should work and if there are lots of repeat queries,
it'll give some actual boost in performance.

= Displaying the relevance score =
Relevanssi stores the relevance score it uses to sort results in the $post variable. Just add
something like

`echo $post->relevance_score`

to your search results template inside a PHP code block to display the relevance score.

= Did you mean? suggestions =
To use Google-style "did you mean?" suggestions, first enable search query logging. The
suggestions are based on logged queries, so without good base of logged queries, the
suggestions will be odd and not very useful.

To use the suggestions, add the following line to your search result template, preferably
before the have_posts() check:

`<?php if (function_exists('relevanssi_didyoumean')) { relevanssi_didyoumean(get_search_query(), "<p>Did you mean: ", "?</p>", 5); }?>`

The first parameter passes the search term, the second is the text before the result,
the third is the text after the result and the number is the amount of search results
necessary to not show suggestions. With the default value of 5, suggestions are not
shown if the search returns more than 5 hits.

= Search shortcode =
Relevanssi also adds a shortcode to help making links to search results. That way users
can easily find more information about a given subject from your blog. The syntax is
simple:

`[search]John Doe[/search]`

This will make the text John Doe a link to search results for John Doe. In case you
want to link to some other search term than the anchor text (necessary in languages
like Finnish), you can use:

`[search term="John Doe"]Mr. John Doe[/search]`

Now the search will be for John Doe, but the anchor says Mr. John Doe.

One more parameter: setting `[search phrase="on"]` will wrap the search term in
quotation marks, making it a phrase. This can be useful in some cases.

= Restricting searches to categories and tags =
Relevanssi supports the hidden input field `cat` to restrict searches to certain categories (or
tags, since those are pretty much the same). Just add a hidden input field named `cat` in your
search form and list the desired category or tag IDs in the `value` field - positive numbers
include those categories and tags, negative numbers exclude them.

This input field can only take one category or tag id (a restriction caused by WordPress, not
Relevanssi). If you need more, use `cats` and use a comma-separated list of category IDs.

The same works with post types. The input fields are called `post_type` and `post_types`.

You can also set the restriction from general plugin settings (and then override it in individual
search forms with the special field). This works with custom taxonomies as well, just replace `cat`
with the name of your taxonomy.

If you want to restrict the search to categories using a dropdown box on the search form, use
a code like this:

`<form method="get" action="<?php bloginfo('url'); ?>">
	<div><label class="screen-reader-text" for="s">Search</label>
	<input type="text" value="<?php the_search_query(); ?>" name="s" id="s" />
<?php
	wp_dropdown_categories(array('show_option_all' => 'All categories'));
?>
	<input type="submit" id="searchsubmit" value="Search" />
	</div>
</form>`

This produces a search form with a dropdown box for categories. Do note that this code won't work
when placed in a Text widget: either place it directly in the template or use a PHP widget plugin
to get a widget that can execute PHP code.

= Restricting searches with taxonomies =

You can use taxonomies to restrict search results to posts and pages tagged with a certain 
taxonomy term. If you have a custom taxonomy of "People" and want to search entries tagged
"John" in this taxonomy, just use `?s=keyword&people=John` in the URL. You should be able to use
an input field in the search form to do this, as well - just name the input field with the name
of the taxonomy you want to use.

It's also possible to do a dropdown for custom taxonomies, using the same function. Just adjust
the arguments like this:

`wp_dropdown_categories(array('show_option_all' => 'All people', 'name' => 'people', 'taxonomy' => 'people'));`

This would do a dropdown box for the "People" taxonomy. The 'name' must be the keyword used in
the URL, while 'taxonomy' has the name of the taxonomy.

= Automatic indexing =
Relevanssi indexes changes in documents as soon as they happen. However, changes in shortcoded
content won't be registered automatically. If you use lots of shortcodes and dynamic content, you
may want to add extra indexing. Here's how to do it:

`if (!wp_next_scheduled('relevanssi_build_index')) {
	wp_schedule_event( time(), 'daily', 'relevanssi_build_index' );
}`

Add the code above in your theme functions.php file so it gets executed. This will cause
WordPress to build the index once a day. This is an untested and unsupported feature that may
cause trouble and corrupt index if your database is large, so use at your own risk. This was
presented at [forum](http://wordpress.org/support/topic/plugin-relevanssi-a-better-search-relevanssi-chron-indexing?replies=2).

= Highlighting terms =
Relevanssi search term highlighting can be used outside search results. You can access the search
term highlighting function directly. This can be used for example to highlight search terms in
structured search result data that comes from custom fields and isn't normally highlighted by
Relevanssi.

Just pass the content you want highlighted through `relevanssi_highlight_terms()` function. The
content to highlight is the first parameter, the search query the second. The content with
highlights is then returned by the function. Use it like this:

`if (function_exists('relevanssi_highlight_terms')) {
    echo relevanssi_highlight_terms($content, get_search_query());
}
else { echo $content; }`

= What is tf * idf weighing? =

It's the basic weighing scheme used in information retrieval. Tf stands for *term frequency*
while idf is *inverted document frequency*. Term frequency is simply the number of times the term
appears in a document, while document frequency is the number of documents in the database where
the term appears.

Thus, the weight of the word for a document increases the more often it appears in the document and
the less often it appears in other documents.

= What are stop words? =

Each document database is full of useless words. All the little words that appear in just about
every document are completely useless for information retrieval purposes. Basically, their
inverted document frequency is really low, so they never have much power in matching. Also,
removing those words helps to make the index smaller and searching faster.

== Known issues and To-do's ==
* Known issue: In general, multiple Loops on the search page may cause surprising results. Please make sure the actual search results are the first loop.
* Known issue: Relevanssi doesn't necessarily play nice with plugins that modify the excerpt. If you're having problems, try using relevanssi_the_excerpt() instead of the_excerpt().
* Known issue: Custom post types and private posts is problematic - I'm using default 'read_private_*s' capability, which might not always work.
* Known issue: There are reported problems with custom posts combined with custom taxonomies, the taxonomy restriction doesn't necessarily work.
* Known issue: Phrase matching is only done to post content; phrases don't match to category titles and other content.
* Known issue: User searches page requires MySQL 5.

* Support for Polylang broke the support for WPML. That is now fixed.
* One deprecated `$wpdb->escape()` was still left; it's gone now.
* Shortcode `layerslider` was causing problems with Relevanssi; Relevanssi now disables it before building excerpts.
* Relevanssi won't break BBPress search anymore.
* If Relevanssi Premium is installed, deleting Relevanssi will not remove the databases and the options.

= 3.1.7 =
* New filter: `relevanssi_comment_content_to_index` lets you modify comment content before it's indexed by Relevanssi (to index comment meta, for example).
* Facetious support: if post_type is set to -1, Relevanssi will not hang up on it.

* Division by zero error caused by 0 in posts_per_page is now prevented, and -1 value for posts_per_page handled better.
* Relevanssi doesn't apply `get_the_excerpt` filters to excerpts it builds any more.
* New filter: `relevanssi_excerpt` lets you modify the excerpts Relevanssi creates.
* Relevanssi now suspends WP post cache while indexing, making indexing a lot more efficient. Thanks to Julien Mession for this one.
* Deprecated function errors in 3.6 removed.
* When search included user profiles or taxonomy terms, Relevanssi would generate lots of MySQL errors. Not anymore.
* New filter: `relevanssi_valid_status` lets you modify the post statuses Relevanssi indexes.
* New filter: `relevanssi_index_taxonomies_args` lets you modify the arguments passed to get_terms() when indexing taxonomies (for example to set 'hide_empty' to false).
* Searching by taxonomy ID could confuse two taxonomies with the same term_id. The search is now checking the taxonomy as well to see it's correct.

* Relevanssi will not choke on bad values of orderby anymore.
* Limit searches is improved: when using AND search it is less likely to miss results.
* Phrase recognition read the whole post content (which it didn't need) from database, causing memory issues in some cases. Fixed that.
* Highlighting was broken, and should work much better now.

* Author search didn't work.
* Fixed an error message caused by all-number synonyms starting with zero, like 02.
* Synonyms are now case-insensitive.

* Fixed undefined variable errors when doing an OR fallback.
* New filter: `relevanssi_bots_to_not_log` makes it possible to block bots from logs. The format matches what other plugins, ie. WP-Useronline, use for bot blocking, so you can share block lists.
* New filter: `relevanssi_admin_search_ok` gives you more control when Relevanssi overrides the default WP search in admin, useful for fixing P2P_Box AJAX search.
* Ordering search results by title or date in admin search works now.
* Modified the way the highlights work; now highlighting words with apostrophes should produce more meaningful results.
* Highlighting should not highlight anything between & and ; or in <style> or <script> tags, thus solving some of the problems related to highlights. Reports of how well this works are welcome.
* On-post highlighting now only highlights content in the loop, so menu texts and other off-the-loop stuff should not get highlights anymore.
* New action hook: `relevanssi_pre_indexing_query` can be used to "SET OPTION SQL_BIG_SELECTS=1" if needed.
* Major indexing problems caused by shortcodes changing the post ID during the indexing of posts are now fixed.
* Relevanssi was being called twice when a post was saved, on `save_post` and `wp_insert_post`. I removed the hook on `save_post`.
* Unsuccessful searches are now ordered by count, like the successful queries are.

= 3.1.4 =
* Choosing which taxonomies to index is now done with an easy-to-use checkbox list.
* Support for WP Table Reloaded and TablePress. Tables created with these plugins will now be expanded and the content indexed by Relevanssi.
* New filter: `relevanssi_index_comments_exclude` can be used to exclude comments from indexing. The filter gets the post ID as a parameter, so you can prevent comments of particular posts being indexed, yet index those posts.
* Relevanssi now adds spaces between tags when creating excerpts to make neater excerpts from tables and other similar situations.
* Relevanssi now indexes unattached attachments, if you choose to index attachments.
* Fixed the problems with Twenty Ten and Twenty Eleven themes better.
* $match->tag now contains the number of tag hits.
* Relevanssi now adds relevance score to posts before passing them to relevanssi_hits_filter. You can find it in $post->relevance_score.
* Tags in breakdowns always showed 0, even though tags were indexed and searched correctly. That's now fixed.

= 3.1.3 =
* AND search did not work in all cases.
* Posts couldn't be found by category name. Fixed that.

= 3.1.2 =
* Exclude category option was broken. Fixed that.
* Searching for a non-existing category ID caused an error. Fixed that.
* Occasional blank screens of death occurred when multibyte string operations weren't installed. That should not happen anymore.
* Fallback to OR search was a bit broken.

= 3.1.1 =
* Small fix to prevent database errors.
* Small fix to prevent disappearing excerpts.

= 3.1 =
* Fixed the uninstalling instructions.
* Fixes a problem with Twenty Ten and Twenty Eleven themes that caused doubled "Continue Reading" links.
* Fixed a notice about undefined variable on plugin update pages.
* Small bug fixes on search to remove warning notices.
* New filter: `relevanssi_index_custom_fields` can be used to modify the list of custom fields to index.
* Deleting menus caused a warning. That is now fixed.
* Relevanssi has an option to disable IP logging (which is actually illegal in some countries). Thanks to Stefan Eufinger.
* Searching in subcategories worked sometimes, but not always. Thanks to Faebu.
* The "Limit searches" option didn't work too well in the case of strong weightings, as it didn't take note of any weights. Now it works better.
* Added a note about disabling custom excerpts when they are not needed - they can slow down the search quite a bit.
* New filter: `relevanssi_options_capability` can be used to modify the capability required to see the options page (default is `manage_options`).
* Fixed the way IDF is calculated to account some extreme cases with small databases.
* New filter: `relevanssi_index_custom_fields` gives added control over which custom fields are indexed.
* Fixed filter: `relevanssi_pre_excerpt_content` wasn't working properly.
* Relevanssi now supports tax_query, for most part. You can query multiple taxonomies, use relation AND and OR, use operators AND, IN and NOT IN and choose include_children (which defaults to true). Old `taxonomy` and `term` still work, but I recommend using tax_query for the level of control it offers.
* Relevanssi now works better with category restrictions. The extra `cats` query variable is no longer necessary, Relevanssi can now read multiple categories from `cat`. You can also use `category__and`, `category__in` and `category__not_in`.
* Same goes with tags: `tags` is now longer necessary. Relevanssi has full support for `tag`, `tag_id`, `tag__and`, `tag__in`, `tag__not_in`, `tag_slug__and`, `tag_slug__in` and `tag_slug__not_in`. For `tag`, both `term1+term2` and `term1,term2` is supported.
* Relevanssi now supports `author_name` and negative values for `author`.
* Relevanssi now supports `offset` query variable.
* Relevanssi now supports meta_query. You can use all comparisons (also EXISTS and NOT EXISTS, even if you don't have WP 3.5). You can also use the older `meta_key` and `meta_value` query variables, including all the comparisons. I have not tested all possible meta_query constructions, so bug reports of things that don't work as expected are welcome.
* New index on the database makes some database operations faster.
* Removed a bug that prevents one-character words from being indexed in titles, despite the minimum word length setting.
* Removed a warning when searching for nothing.
* Fixes a warning about $wpdb->prepare() caused by a change in WordPress 3.5.

* Fixed a major bug that caused the searches to fail when "Limit searches" was enabled, but "Limit" was not defined.
* Modified `relevanssi_remove_punct()` to replace curly apostrophes and quotes with spaces instead of removing them, to make the index more consistent (regular apostrophes were replaced with spaces). Reindexing the database is a good idea.

* Removed an error message about set_time_limit() under safe_mode.
* Jetpack Contact Form shortcode caused problems when indexing. Relevanssi will now simply remove the shortcode before indexing.

* Searching for pages in admin didn't work properly. Fixed that.
* Fixed warnings for undefined variables.

* New shortcode: use shortcode `noindex` to wrap parts of posts you want to keep from the index.
* And a bunch of other changes.

= 2.9.14 =
* Relevanssi will now index pending and future posts. These posts are only shown in the admin search.

* New filter `relevanssi_results` added. This filter will process an array with (post->ID => document weight) pairs.
* Private and draft posts were deleted from the index when they were edited. This bug has been fixed. (Thanks to comprock.)

* Fixed problems with searching attachments. Indexing attachments still has some problems. When you build the index, attachments are indexed properly.

= 2.4 =
* Highlighting post content won't highlight inside HTML tags anymore.

* Phrases are now matched also in post titles and category titles (before they were only matched against post content).
* Post excerpts can now be indexed and searched. I would appreciate feedback from people who use this feature: do you use the excerpts in search results? If you use custom snippets created by Relevanssi, what you want them to display?
* Set the constant TIMER to true to enable timing of the search process for debugging reasons.

= 2.1.6 =

= 2.1.4 =
* Fixed a small bug that could cause all queries by anonymous users to go unlogged.

= 2.1.3 =
* OR operator makes a comeback! The default operator is now an option, and if you choose AND and search gets no results, an OR search is also run.
* You can now give a list of user ids - any searches by those users will not be logged. List your admin user id, so your test searches won't clutter the log.

= 2.1.2 =
* Removing punctuation didn't work properly, making phrase search impossible. I'd thought I'd fix it, but for some reason I made a mistake and the fix didn't appear in the released versions.
* Search has now an implicit AND operator, which means that every search term must appear in all result documents. Please let me know if you'd prefer an implicit OR operator, like Relevanssi had before.
* Relevanssi options page now shows the amount of indexed documents, making troubleshooting indexing easier.

= 2.1.1 =

* Custom taxonomies can also be indexed in addition to standard post tags. Default behaviour is to index nothing. If somebody knows a way to list all custom taxonomies, that information would be appreciated.

= 1.7.3 =
* Small bug fix: code that created database indexes was broken. Say "ALTER TABLE `wp_relevanssi` ADD INDEX (doc)" and "ALTER TABLE `wp_relevanssi` ADD INDEX (term)" to your MySQL db to fix this for an existing installation.

= 1.7.2 =
* Small bug fix: public posts that are changed to private are now removed from index (password protected posts remain in index).
* An Italian translation is now included (thanks to Alessandro Fiorotto).

= 1.7.1 =
* Small fix: the hidden variable cat now accepts negative category and tag ids. Negative categories and tags are excluded in search. Mixing inclusion and exclusion is possible.

= 1.7 =
* Major bug fix: Relevanssi doesn't kill other post loops on the search result page anymore. Please let me know if Relevanssi feels too slow after the update.
