<p>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.</p>
<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>
<p>This plugin is under active development on GitHub:</p>
<p><a href="https://github.com/pantheon-systems/solr-power" rel="nofollow ugc">https://github.com/pantheon-systems/solr-power</a></p>
<p>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.</p>
<p>For further documentation, such as available filters and working with the <code>SolrPower_Api</code> class directly, please see the project wiki:</p>
<p><a href="https://github.com/pantheon-systems/solr-power/wiki" rel="nofollow ugc">https://github.com/pantheon-systems/solr-power/wiki</a></p>
<p>You may notice there are two sets of tests running, on two different services:</p>
<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>
<p>Both of these test suites can be run locally, with a varying amount of setup.</p>
<p>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.</p>
<p>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.</p>
<p>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></p>
<h3>WP-CLI Support</h3>
<p>This plugin has <a href="http://wp-cli.org/" rel="nofollow ugc">WP-CLI</a> support.</p>
<p>All Solr Power related commands are grouped into the <code>wp solr</code> command, see an example:</p>
<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>
<p>You can see more details about the commands using <code>wp help solr</code>:</p>
<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>
<p>Use Solr in a custom WP_Query instead of querying a database. Add <code>'solr_integrate' => true</code> to the query arguments.</p>
<p><strong>NOTE:</strong> 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.</p>
<p>A meta_query can use the following compare operators:</p>
<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>
<p>(<code>'REGEXP'</code>, <code>'NOT REGEXP'</code>, and <code>'RLIKE'</code> are not supported.)</p>
<h3>Configuration Tips</h3>
</p>
<p><h4>Searching by author name</h4>
</p>
<p>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>:</p>
<pre><code>  <copyField source="post_author" dest="text"/>
</code></pre>
<p><h4>Boosting relevancy score by publish date</h4>
</p>
<p>The following guidance can be used to extend the Solr index and modify boosts beyond just this example.</p>
<p>To support math functions on dates, you must add a custom <code>schema.xml</code> to Solr and <strong>reindex with the new schema</strong>.</p>
<p>Add the following to <code>schema.xml</code>:</p>
<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>
<p>Add the following to your <code>functions.php</code> file.</p>
<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 $dismax;
  }
  add_filter( 'solr_dismax_query', 'my_solr_dismax_query' );
</code></pre>
<p><h4><code>is_solr_query</code> Filter</h4>
</p>
<p>The <code>is_solr_query</code> filter controls whether Solr should be used for a specific query.</p>
<p>Parameters:</p>
<ul>
<li>$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>
<p>Return:</p>
<ul>
<li>
<p>bool: true to enable Solr for the query, false to disable it.</p>
<p>add_filter( ‘is_solr_query’, function( $enabled, $query ) {<br />
    if ( $query->is_category( ‘news’ ) ) {<br />
        return false;<br />
    }<br />
    return $enabled;<br />
}, 10, 2 );</p>
</li>
</ul>
<p><h4>Custom schema file path</h4>
</p>
<p>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.</p>
<p>Parameters:<br />
* $custom_schema_file_path (string): Default path to a custom schema file</p>
<p>Return:<br />
* string: Absolute path to a custom schema.xml file.</p>
<pre><code>add_filter('solr_power_customer_schema_file_path', function($custom_schema_file_path) {
    return '/absolute/path/to/schema.xml';
});
</code></pre>
<p><h4>Common issues</h4>
</p>
<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>
<p><h4>Explicit Commit vs Autocommit</h4>
</p>
<p>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.</p>
<p>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.</p>
<p>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.</p>
<p>To enable autocommit, add the following to <code>wp-config.php</code> or an mu-plugin.</p>
<pre><code>  define( 'SOLRPOWER_DISABLE_AUTOCOMMIT', false );
</code></pre>
<p>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.</p>
<pre><code>  wp solr commit
</code></pre>

Solr Search for WordPress


This plugin is intended for use with sites hosted on Pantheon, and may not work with other hosting platforms.



This plugin replaces the default search mechanism within WordPress while preserving the familiar integration methods within themes and widgets.  The plugin also included a widget that you can use to integrate with the current theme


Awesome, work !!!

Improve your user experience with the Apache Solr search engine for your WordPress website.

<p>Search Regex adds a powerful set of search and replace functions to WordPress posts, pages, custom post types, and other data sources. These go beyond the standard searching capabilities, and allow you to search and replace almost any data stored on your site. In addition to simple searches you have the full power of PHP’s regular expressions at your disposal.</p>
<p>You can use this to do things like:<br />
– Help migrate a site from one domain to another<br />
– Update URLs in links and images<br />
– Perform site-wide changes</p>
<p>Search filters can be created to match any column of any WordPress table. For example:<br />
– Find all posts in a category<br />
– Find all post meta data without a post<br />
– Find all posts in a date range</p>
<p>Search Regex handles small and large sites.</p>
<p>Search Regex has been tested with PHP from 7.4 to 8.4.</p>
<h3>What can I search?</h3>
<p>You can search:<br />
– Posts<br />
– Pages<br />
– Any custom post type<br />
– Comments (including spam)<br />
– Users<br />
– Meta data<br />
– WordPress options</p>
<p>Full regular expression support is provided, and you can capture data and use it in the replacement.</p>
<h3>Actions</h3>
<p>A variety of actions can be performed on matching results:<br />
– Modify and replace the result<br />
– Delete the result<br />
– Export to CSV and SQL<br />
– Perform custom PHP action</p>
<h3>Modify and Replace Data</h3>
<p>Results can be individually modified by clicking on the item to change, and using the popup modifier.</p>
<p>Bulk modifications can be performed against all matching results.</p>
<p>The types of modification depend on the data being changed:<br />
– Numbers can be added or subtracted to existing numbers<br />
– Hours, days, weeks, and months, can be added to dates<br />
– Tags and categories can be added, removed, and substitued</p>
<p>Custom shortcodes are supported that allow dynamic data to be included:<br />
– Add the current date and time, in any format, to content<br />
– Insert data from other columns. For example, insert the category into the title<br />
– Transform existing data. For example, convert case, change underscores to dashes.</p>
<h3>Example uses</h3>
<p>Some ideas for potential uses:<br />
– Delete all comments that match a phrase<br />
– Add a category to all matching posts<br />
– Remove orphaned meta data</p>

Search Regex


Incredibly powerful search tool for your dashboard, especially useful if, for example, you've moved to a new server (or a new site structure), or someone's changed their name, or any other reason you might need to update a lot of things at once in the same way. Risky too - make sure you preview any replacements first!


Incredibly powerful!

Search Regex adds a powerful set of search and replace functions to WordPress posts, pages, custom post types, and other data.
