<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>With an intuitive interface, you can perform detailed find and replace operations across your entire database. Select specific tables, toggle case sensitivity, and preview changes before committing. Serialized data is fully supported. Designed to handle large websites, this plugin operates smoothly without the need for external tools.</p>
<h4>Features Include</h4>
<ul>
<li><strong>Text Replacement</strong> – Find and replace text across multiple database tables with support for serialized data and options for case-sensitive search.</li>
<li><strong>Replace Image</strong> – Directly replace images from the media library, automatically regenerating thumbnails to ensure visual consistency.</li>
<li><strong>Replace Media</strong> – Manage and replace media files of various formats across your entire site.</li>
<li><strong>Preview Changes</strong> – Always see a “dry-run” preview of the changes to ensure accuracy before applying them.</li>
<li><strong>Large Sites Supported</strong> – Optimized for performance, capable of handling large databases efficiently.</li>

<h4>Tips for Using Search & Replace</h4>
<p><strong>Backup Your Database</strong> – While the plugin is safe to use, it’s always a good idea to make a backup before making changes.</p>
<p>Common mistakes to avoid when replacing text:</p>
<ul>
<li>Partial Matches – Ensure that you’re not replacing partial matches that could affect unintended content. For example, replacing “cat” could affect “category” or “concatenate”.</li>
<li>Case Sensitivity – Be mindful of case sensitivity when replacing text. If you’re looking to replace “Cat” with “Dog”, ensure that you’re not affecting “cat” or “CAT”.</li>
<li>URL Replacements – Always use the same format for both the search and replace values. For example if your search term has a trailing slash, ensure that the replacement term also has a trailing slash. E.g., “example.com/” to “example.net/” instead of “example.com/” to “example.net”.</li>
</ul>
<h4>Getting Started</h4>
<p>After installing Search & Replace Everything by WPCode, look for the new menu item under <code>WP Admin > Tools > WP Search & Replace</code>. From there, you can start managing your content and perform find and replace operations for text or images across your entire website.</p>
