Demo

Getting started

• Place the following code in a file called search.json in the root of your Jekyll blog. This file will be used as a small data source to perform the searches on the client side:

---
---
[
  {% for post in site.posts %}
    {
      "title"    : "{{ post.title | escape }}",
      "category" : "{{ post.category }}",
      "tags"     : "{{ post.tags | join: ', ' }}",
      "url"      : "{{ site.baseurl }}{{ post.url }}",
      "date"     : "{{ post.date }}"
    } {% unless forloop.last %},{% endunless %}
  {% endfor %}
]

• configure the library ( options )

Enabling full-text search

Note that the index generated in search.json does not include the posts' content since you may not want to load the whole content of your blog in each single page. However, if some of you want to enable full-text search, you can still add the posts' content to the index, either to the normal search, or on an additional search page with a dedicated second index file. To do this, simply add

"content"  : "{{ post.content | strip_html | strip_newlines }}"

to search.json after the "date" line to which you must add a comma (,).

Install with bower

bower install simple-jekyll-search

Setup

You need to place the following code within the layout where you want he search to appear.

For example in _layouts/default.html:

<!-- Html Elements for Search -->
<div id="search-container">
<input type="text" id="search-input" placeholder="search...">
<ul id="results-container"></ul>
</div>

<!-- Script pointing to jekyll-search.js -->
<script src="{{ site.baseurl }}/bower_components/simple-jekyll-search/dest/jekyll-search.js" type="text/javascript"></script>

Options

Customize SimpleJekyllSearch by passing in your configuration options:

SimpleJekyllSearch({
  searchInput: document.getElementById('search-input'),
  resultsContainer: document.getElementById('results-container'),
  json: '/search.json',
})

The above initialization needs to occur after the inclusion of jekyll-search.js.

searchInput (Element) [required]

The input element on which the plugin should listen for keyboard event and trigger the searching and rendering for articles.

resultsContainer (Element) [required]

The container element in which the search results should be rendered in. Typically an <ul>.

json (String|JSON) [required]

You can either pass in an URL to the search.json file, or the results in form of JSON directly, to save one round trip to get the data.

searchResultTemplate

The template of a single rendered search result.

The templating syntax is very simple: You just enclose the properties you want to replace with curly braces.

E.g.

The template

<li><a href="{url}">{title}</a></li>

will render to the following

<li><a href="/jekyll/update/2014/11/01/welcome-to-jekyll.html">Welcome to Jekyll!</a></li>

If the search.json contains this data

[

    {
      "title"    : "Welcome to Jekyll!",
      "category" : "",
      "tags"     : "",
      "url"      : "/jekyll/update/2014/11/01/welcome-to-jekyll.html",
      "date"     : "2014-11-01 21:07:22 +0100"
    }

]

noResultsText

The HTML that will be shown if the query didn't match anything.

limit

You can limit the number of posts rendered on the page.

fuzzy

Enable fuzzy search to allow less restrictive matching.

exclude

Pass in a list of terms you want to exclude (terms will be matched against a regex, so urls, words are allowed).

Enable full content search of posts and pages

• Replace 'search.json' with the following code:

---
layout: null
---
[
  {% for post in site.posts %}
    {
      "title"    : "{{ post.title | escape }}",
      "category" : "{{ post.category }}",
      "tags"     : "{{ post.tags | join: ', ' }}",
      "url"      : "{{ site.baseurl }}{{ post.url }}",
      "date"     : "{{ post.date }}",
      "content"  : "{{ post.content | strip_html | strip_newlines }}"
    } {% unless forloop.last %},{% endunless %}
  {% endfor %}
  ,
  {% for page in site.pages %}
   {
     {% if page.title != nil %}
        "title"    : "{{ page.title | escape }}",
        "category" : "{{ page.category }}",
        "tags"     : "{{ page.tags | join: ', ' }}",
        "url"      : "{{ site.baseurl }}{{ page.url }}",
        "date"     : "{{ page.date }}",
        "content"  : "{{ page.content | strip_html | strip_newlines }}"
     {% endif %}
   } {% unless forloop.last %},{% endunless %}
  {% endfor %}
]

If search isn't working due to invalid JSON

• There is a filter plugin in the _plugins folder which should remove most characters that cause invalid JSON. To use it, add the simple_search_filter.rb file to your _plugins folder, and use remove_chars as a filter.

For example: in search.json, replace

"content"  : "{{ page.content | strip_html | strip_newlines }}"

with

"content"  : "{{ page.content | strip_html | strip_newlines | remove_chars | escape }}"

##Browser support

Browser support should be about IE6+ with this addEventListener shim

Dev setup

• npm install the dependencies.

• gulp watch during development

• npm test or npm run watch-test to run the unit tests
