Search
Just the Docs uses lunr.js to add a client-side search interface powered by a JSON index that Jekyll generates. All search results are shown in an auto-complete style interface (there is no search results page). By default, all generated HTML pages are indexed using the following data points:
- Page title
- Page content
- Page URL
Enable search in configuration
In your site’s _config.yml, enable search:
# Enable or disable the site search
# Supports true (default) or false
search_enabled: true
Search granularity
Pages are split into sections that can be searched individually. The sections are defined by the headings on the page. Each section is displayed in a separate search result.
# Split pages into sections that can be searched individually
# Supports 1 - 6, default: 2
search.heading_level: 2
Search previews
A search result can contain previews that show where the search words are found in the specific section.
# Maximum amount of previews per search result
# Default: 3
search.previews: 3
# Maximum amount of words to display before a matched word in the preview
# Default: 5
search.preview_words_before: 5
# Maximum amount of words to display after a matched word in the preview
# Default: 10
search.preview_words_after: 10
Search tokenizer
The default is for hyphens to separate tokens in search terms: gem-based is equivalent to gem based, matching either word. To allow search for hyphenated words:
# Set the search token separator
# Default: /[\s\-/]+/
# Example: enable support for hyphenated search words
search.tokenizer_separator: /[\s/]+/
Display URL in search results
# Display the relative url in search results
# Supports true (default) or false
search.rel_url: false
Display search button
The search button displays in the bottom right corner of the screen and triggers the search input when clicked.
# Enable or disable the search button that appears in the bottom right corner of every page
# Supports true or false (default)
search.button: true
Hiding pages from search
Sometimes you might have a page that you don’t want to be indexed for the search nor to show up in search results, e.g, a 404 page. To exclude a page from search, add the search_exclude: true parameter to the page’s YAML front matter:
Example
---
layout: default
title: Page not found
nav_exclude: true
search_exclude: true
---
Generate search index when used as a gem
If you use Just the Docs as a remote theme, you do not need the following steps.
If you use the theme as a gem, you must initialize the search by running this rake command that comes with just-the-docs:
$ bundle exec just-the-docs rake search:init
This command creates the assets/js/zzzz-search-data.json file that Jekyll uses to create your search index. Alternatively, you can create the file manually with this content.
