Search is critical for your site, but the default search for WordPress leaves a lot to be desired. Improve your user experience with the Apache Solr search engine for your WordPress website.
<ul>
<li>Fast results, with better accuracy.</li>
<li>Enables faceting on fields such as tags, categories, author, and page type.</li>
<li>Indexing and faceting on custom fields.</li>
<li>Drop-in support for <a href="https://codex.wordpress.org/Class_Reference/WP_Query" rel="nofollow ugc">WP_Query</a> with the <code>solr_integrate</code> parameter set to true.</li>
<li>Completely replaces default WordPress search, just install and configure.</li>
<li>Completely integrated into default WordPress theme and search widget.</li>
<li>Very developer-friendly: uses the modern <a href="http://www.solarium-project.org/" rel="nofollow ugc">Solarium</a> library</li>
</ul>
<h3>Development</h3>
This plugin is under active development on GitHub:
<a href="https://github.com/pantheon-systems/solr-power" rel="nofollow ugc">https://github.com/pantheon-systems/solr-power</a>
Please feel free to file issues there. Pull requests are also welcome! See <a href="https://github.com/pantheon-systems/solr-power/blob/main/CONTRIBUTING.md" rel="nofollow ugc">CONTRIBUTING.md</a> for information on contributing.
For further documentation, such as available filters and working with the <code>SolrPower_Api</code> class directly, please see the project wiki:
<a href="https://github.com/pantheon-systems/solr-power/wiki" rel="nofollow ugc">https://github.com/pantheon-systems/solr-power/wiki</a>
You may notice there are two sets of tests running, on two different services:
<ul>
<li><a href="https://phpunit.de/" rel="nofollow ugc">PHPUnit</a> test suite against a Solr instance.</li>
<li>The <a href="http://behat.org/" rel="nofollow ugc">Behat</a> test suite against a Pantheon site, to ensure the plugin’s compatibility with the Pantheon platform.</li>
</ul>
Both of these test suites can be run locally, with a varying amount of setup.
PHPUnit requires the <a href="https://make.wordpress.org/core/handbook/testing/automated-testing/phpunit/" rel="nofollow ugc">WordPress PHPUnit test suite</a>, and access to a database with name <code>wordpress_test</code>. If you haven’t already configured the test suite locally, you can run <code>bash bin/install-wp-tests.sh wordpress_test root '' localhost</code>. You’ll also need access to a running Solr instance, in order to run the unit tests against Solr.
Behat requires a Pantheon site with Solr enabled. Once you’ve created the site, you’ll need <a href="https://github.com/pantheon-systems/terminus#installation" rel="nofollow ugc">install Terminus</a>, and set the <code>TERMINUS_TOKEN</code>, <code>TERMINUS_SITE</code>, and <code>TERMINUS_ENV</code> environment variables. Then, you can run <code>./bin/behat-prepare.sh</code> to prepare the site for the test suite.
Note that dependencies are installed via Composer and the <code>vendor</code> directory is not committed to the repository. You will need to run <code>composer install</code> locally for the plugin to function. You can read more about Composer <a href="https://getcomposer.org" rel="nofollow ugc">here</a>
<h3>WP-CLI Support</h3>
This plugin has <a href="http://wp-cli.org/" rel="nofollow ugc">WP-CLI</a> support.
All Solr Power related commands are grouped into the <code>wp solr</code> command, see an example:
<pre><code>$ wp solr
usage: wp solr check-server-settings
 or: wp solr delete [<id>...] [--all]
 or: wp solr index [--batch=<batch>] [--batch_size=<size>] [--post_type=<post-type>]
 or: wp solr info [--field=<field>] [--format=<format>]
 or: wp solr optimize-index
 or: wp solr repost-schema
 or: wp solr stats [--field=<field>] [--format=<format>]

See 'wp help solr <command>' for more information on a specific command.
</code></pre>
You can see more details about the commands using <code>wp help solr</code>:
<pre><code>**NAME**

 wp solr

**DESCRIPTION**

 Perform a variety of actions against your Solr instance.

**SYNOPSIS**

 wp solr <command>

**SUBCOMMANDS**

 check-server-settings Check server settings.
 delete Remove one or more posts from the index.
 index Index all posts for a site.
 info Report information about Solr Power configuration.
 optimize-index Optimize the Solr index.
 repost-schema Repost schema.xml to Solr.
 stats Report stats about indexed content.<h3>WP_Query Integration</h3>
</code></pre>
Use Solr in a custom WP_Query instead of querying a database. Add <code>'solr_integrate' => true</code> to the query arguments.
NOTE: Currently, only basic queries, tax_query, meta_query and date_query are supported. See <code>examples/example.custom_WP_Query.php</code> for an example.
A meta_query can use the following compare operators:
<ul>
<li><code>'='</code></li>
<li><code>'!='</code></li>
<li><code>'>'</code></li>
<li><code>'>='</code></li>
<li><code>'<'</code></li>
<li><code>'<='</code></li>
<li><code>'LIKE'</code></li>
<li><code>'NOT LIKE'</code></li>
<li><code>'IN'</code></li>
<li><code>'NOT IN'</code></li>
<li><code>'BETWEEN'</code></li>
<li><code>'NOT BETWEEN'</code></li>
<li><code>'EXISTS'</code></li>
<li><code>'NOT EXISTS'</code></li>
</ul>
(<code>'REGEXP'</code>, <code>'NOT REGEXP'</code>, and <code>'RLIKE'</code> are not supported.)
<h3>Configuration Tips</h3>

<h4>Searching by author name</h4>

To support searching by author name (e.g. where “Pantheon” would return posts authored by the “Pantheon” user), add the following to your custom <code>schema.xml</code>:
<pre><code> <copyField source="post_author" dest="text"/>
</code></pre>
<h4>Boosting relevancy score by publish date</h4>

The following guidance can be used to extend the Solr index and modify boosts beyond just this example.
To support math functions on dates, you must add a custom <code>schema.xml</code> to Solr and reindex with the new schema.
Add the following to <code>schema.xml</code>:
<pre><code> 
 
 <fieldType name="tdate" class="solr.TrieDateField" omitNorms="true" precisionStep="6" positionIncrementGap="0"/>

 
 <field name="post_date_iso" type="tdate" indexed="true" stored="true" required="true" />
</code></pre>
Add the following to your <code>functions.php</code> file.
<pre><code> <?php
 /**
 * Hooks into the document build process to add post date field in proper format.
 */
 function my_solr_build_document( $doc, $post_info ) {
 $post_time = strtotime( $post_info->post_date );
 // Matches format required for TrieDateField
 $doc->setField( 'post_date_iso', gmdate( 'c\Z', $post_time ) );
 return $doc;
 }
 add_filter( 'solr_build_document', 'my_solr_build_document', 10, 2 );

 /**
 * Hooks into query processor, Dismax, to add publish date boost.
 * See: https://www.metaltoad.com/blog/date-boosting-solr-drupal-search-results
 */
 function my_solr_dismax_query( $dismax ) {
 $dismax->setQueryParser( 'edismax' );
 $dismax->setBoostQuery( 'recip(abs(ms(NOW/HOUR,post_date_iso),3.16e-11,1,1))' );
 return $dismax;
 }
 add_filter( 'solr_dismax_query', 'my_solr_dismax_query' );
</code></pre>
<h4><code>is_solr_query</code> Filter</h4>

The <code>is_solr_query</code> filter controls whether Solr should be used for a specific query.
Parameters:
<ul>
<li>$enabled (bool): Indicates whether Solr should be used for the query. Defaults to true if the query is a search or if solr_integrate is set in the query.</li>
<li>$query (WP_Query): The current WordPress query object.</li>
</ul>
Return:
<ul>
<li>
bool: true to enable Solr for the query, false to disable it.
add_filter( ‘is_solr_query’, function( $enabled, $query ) { 
 if ( $query->is_category( ‘news’ ) ) { 
 return false; 
 } 
 return $enabled; 
}, 10, 2 );
</li>
</ul>
<h4>Custom schema file path</h4>

By default, custom schema is sourced from <code>wp-content/uploads/solr-for-wordpress-on-pantheon/schema.xml</code>. This can be overridden with an absolute path using the the <code>solr_power_customer_schema_file_path</code> filter.
Parameters: 
* $custom_schema_file_path (string): Default path to a custom schema file
Return: 
* string: Absolute path to a custom schema.xml file.
<pre><code>add_filter('solr_power_customer_schema_file_path', function($custom_schema_file_path) {
 return '/absolute/path/to/schema.xml';
});
</code></pre>
<h4>Common issues</h4>

<ul>
<li>Failing to post the schema.xml will result in an error during indexing, “Missing <code>post_date_iso</code> field.”</li>
<li>If you have the field and type in the schema, but don’t add the <code>solr_build_document</code> filter, you will get a similar error.</li>
<li>If the <code>post_date_iso</code> field is missing from the index, Solr will ignore this boost and return regular results.</li>
<li>Trying to use a regular date field for the boost query will result in an error in the request instead of results.</li>
</ul>
<h4>Explicit Commit vs Autocommit</h4>

Once solr has sent the data to the solr server, solr must COMMIT the data to the index and adjust the index and relevancy ratings accordingly before that data can appear in search results.
By default, Solr Search for WordPress has auto-commit disabled. The index is committed when the uncommitted item is two minutes old, or the cron runs. By default, the cron runs on the Pantheon platform every hour.
When autocommit is enabled, Solr Search for WordPress commits data when it sends every post. When running on Pantheon, we recommend leaving autocommit disabled to aid overall site performance.
To enable autocommit, add the following to <code>wp-config.php</code> or an mu-plugin.
<pre><code> define( 'SOLRPOWER_DISABLE_AUTOCOMMIT', false );
</code></pre>
To force-commit data outside of a normal cron run, from the command line, you can run the command below or simply force a cron-run.
<pre><code> wp solr commit
</code></pre>

Search & Filter

Great Plugin

I use the pro version of this plugin and it is truly one of the best, most useful plugins out there. There's no bloat. It doesn't load you down with a bunch of crappy templates or anything like that. It just focuses on providing you all the options you could need for searching and filtering content and leaves the rest to you. I am always pleasantly surprised that when I want to do some weird thing with filtering I find that this plugin already has the ability to do it. 

Search Filter PRO


Excellent plugin with very good ACF support in its pro version but also a very useful Elementor integration. The support is very responsive and very helpful!Great job !


Excellent plugin with excellent support

I would love to say this plugin is awesome. I really would. It has some great functionality out of the box. I need to drop it a star and a half because it overlooks a few fundamental priorities that would be easy to fix but they don's seem to want to bother with. First, their is no way to alter the html template of the outputted form, or give you a way to segment it into sections. This creates a huge drag trying to style a single flowing list of elements <ul><li></li></ul>. This would be easy to solve and there are several requests for styling help. Second, the pro support is not very good. I was not able to find a way to contact them on my account page so came and left a review instead.

Pretty Good functionality but styling help is non-existant
