The SearchParserFunction extension adds a parser function to search, format and display search results in wiki pages.

Installation

• Download and move the extracted SearchParserFunction folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/SearchParserFunction
• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'SearchParserFunction' );
  

•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Usage

Basic usage

{{#search:foo}}

This will search for pages that contain "foo" and return the results as a list of links, like so:

• Foo
• Bar
• Baz

You can use all available search operators. For example, if you're using CirrusSearch:

{{#search:foo incategory:Bar linksto:Baz}}

See Help:CirrusSearch for all available search operators (or Help:Searching if you're not using CirrusSearch).

Note! The current page will be excluded from the search results.

Parameters

• namespace - Namespace to search, defaults to 0 (see namespace constants). Separate multiple values with commas.
• limit - Max number of results, either an integer or 'max', defaults to 10.
• offset - Number of results to skip, defaults to 0, useful to access results beyond the 'max' limit.
• profile - Ranking algorithm to use, defaults to let the engine decide.
• what - Type of search to perform, either 'text', 'title' or 'nearmatch', defaults to 'text'.
• interwiki - Include interwiki results in the search, if available.
• rewrites - Enable internal query rewriting, for example to correct spelling mistakes.
• sort - Sorting criteria, defaults to 'relevance'.
• format - Format of the search results, defaults to 'list' (see below for more).

For example, to get the name of the latest file that has "foo" in the title:

{{#search: foo
| namespace = 6
| limit = 1
| what = title
| sort = create_timestamp_asc
| format = plain
}}

Formats

List

Returns an unordered list (<ul>) of search results, linked to their pages. For example:

• Foo
• Bar
• Baz

Count

Returns the total number of search results as a plain number.

Plain

Returns a comma-separated list of plain titles, for example:

Foo, Bar, Baz

This format is designed for further processing. For example, using the #arraymap function of Extension:PageForms:

{{#arraymap: {{#search:foo}} | , | @ | [[@]] | <br> }}

This would output the search results one below the other and linked to their pages, like so:

Foo
Bar
Baz

If some of the titles contain commas, you can change the separator like so:

{{#search:foo|separator=;}}

JSON

Returns a JSON object for further processing, for example in a Lua module.

Note that this format returns the entire output from the Search API, not just the search results.

Template

Returns the search results wrapped in a template. The search result title is passed to the template as an unnamed parameter {{{1}}} and may be used or ignored.

For example, if a template named "Search result" contained the following:

<div style="border: 1px solid #aaa; border-radius: 10px; margin: 1em 0; padding: 1em; max-width: 600px;">
<big>[[{{{1}}}]]</big>
<p>{{fullurl:{{{1}}}}}</p>
</div>

Then a query like the following:

{{#search: foo
| format = template
| template = Search result
}}

Would output the following:

Foo

https://www.mediawiki.org/wiki/Foo

Bar

https://www.mediawiki.org/wiki/Bar

Baz

https://www.mediawiki.org/wiki/Baz
