Solr Search Module

A module that adds the ability to index content in a Solr instances, and to then search that content.

Provides a SolrSearchPage type that allows CMS authors to configure a search page within the CMS to display results without needing to perform code behind to determine how the search works.

Version Information

  • The 2.0 branch is compatible with SilverStripe 3.0
  • The master branch is compatible with SilverStripe 3.1

Requirements

Quick Usage Overview

Install Solr (packages available for most OSes)

For demonstration and testing purposes, a standalone Jetty based installation of solr is available in the solr/ subdirectory. To execute, simply change to that directory and run java -jar start.jar - the default settings will be fine for evaluation.

If you are running a custom Solr instance, make sure to copy the solr/solr/solr/conf/schema.xml file to your solr instance - there are a couple of custom types defined that SilverStripe uses.

If you have a configuration different to the default locahost:8983/solr configuration, you can configure things by calling

SolrSearchService::$solr_details = array();

Add the extension to your pages

Add the SolrIndexable extension to any SiteTree objects you want to search. Support for other data objects may work, though file indexing is not yet supported

Object::add_extension('SiteTree', 'SolrIndexable');

By default, the solr indexer will index Title and Content fields. If you want other fields indexed too, add them to your $searchable_fields static variable in your class type.

There is also an optional set of extensions available if you wish to enable an additional SiteTree index based on user permissions (rather than filtering the search result's response).

This will require the Queued Jobs module to function, due to the recursive indexing when saving a page. https://github.com/silverstripe-australia/silverstripe-queuedjobs

Object::add_extension('SiteTree', 'SiteTreePermissionIndexExtension');
Object::add_extension('SolrSearchPage', 'SolrSearchPagePermissionIndexExtension');

Configure your search page

This module creates a new page of type SolrSearchPage in your site's root. This should be published before being able to perform searches.

Add the search extension

Finally, the search mechanism needs to be hooked up to your pages. This can be done by adding the SolrSearchExtension to your Page_Controller class to make available the various template hooks

Object::add_extension('Page_Controller', 'SolrSearchExtension');

Now, add your searchform wherever you like in your Page template using $SearchForm

Using facets

First, you need to tell the search page what you're going to be faceting on

SolrSearchPage::$facets = array('MetaKeywords_ms');

then make sure that field (MetaKeywords) is included in the list of fields to index via the searchable_fields static.

*_ms represents a multivalue field. *_as represents a sortable field (which doesn't require tokenization).

Template options

To customise search results display, provide a SolrSearchPage_results.ss file in your theme's templates directory.

Administration

If you have ADMIN privileges, you can start and stop the locally bundled jetty version of solr from within the CMS on the Solr admin section.

To set the java path (if different from /usr/bin/java), set

SolrSearchService::$java_bin

to the appropriate path

Troubleshooting

If you aren't getting any search results, first make sure Solr is running and has been indexed.
