<p>Relevanssi replaces the standard WordPress search with a better search engine, with lots of features and configurable options. You’ll get better results, better presentation of results – your users will thank you.</p>
<p>This is the free version of Relevanssi. There’s also Relevanssi Premium, which has added features. For more information about Premium, see <a href="https://www.relevanssi.com/" rel="nofollow ugc">Relevanssi.com</a>.</p>
<p>Do note that using Relevanssi may require large amounts (hundreds of megabytes) of database space (for a reasonable estimate, multiply the size of your <code>wp_posts</code> database table by three). If your hosting setup has a limited amount of space for database tables, using Relevanssi may cause problems. In those cases use of Relevanssi cannot be recommended.</p>

Relevanssi – A Better Search

I cannot understand why Relevanssi does not have more active installs, since the years it's the best plugin to sort the WP search results by Relevancy.

I would like to see 1 million installs soon, it deserves.

Best Plugin to improve the WordPress Search Engine

I rarely find a plugin that does exactly what I need, clearly and efficiently (therefore, I usually build it myself). The various but smooth settings allow a perfect fine tuning: nothing more and nothing less than what is really needed. My compliments!

Just perfect!

Relevanssi replaces the default search with a partial-match search that sorts results by relevance. It also indexes comments and shortcode content.

<p>Visitors are finding your website, but they are not finding your products and content.</p>
<ul>
<li>FoundThis lets website visitors search your website, in their own language.</li>
<li>Users can type in any search term, in any language.  It then auto-translates the search query to your site language.</li>
<li>It then expands your website’s search using AI, ensuring that your products and content is always found.</li>
<li>Searches are logged, so that you can gain intelligence on what your visitors are actually searching for, allowing you to optimize your products and content.</li>
<li>Works with all WordPress e-Commerce plugins, including WooCommerce.</li>
<li>Lets international visitors find what they want on your website.</li>
<li>Allows for any searches in any language.</li>
</ul>
<p>The plugin is designed to be:</p>
<ul>
<li>Opt-in (you must enable optimization)</li>
<li>Fail-open (if the API is unavailable, WordPress search remains unchanged)</li>
</ul>
<h3>External services</h3>
<ul>
<li>This plugin connects to the FoundThis API to translate search queries.</li>
<li>Pro Version expands the search query using AI, ensuring your client always finds your products in your shop catalog as well as any content on your site.</li>
</ul>
<p>Service: FoundThis API<br />
– Service URL: https://api.foundthis.us/</p>
<p>Endpoints used by this plugin:<br />
– API key registration: https://api.foundthis.us/api/v1/store/register<br />
– Connection diagnostics: https://api.foundthis.us/api/v1/store/status<br />
– Search optimization: https://api.foundthis.us/api/v1/query/interpret</p>
<p>Data sent:<br />
– Search query text<br />
– Site language<br />
– Store identifier</p>
<p>Why the store identifier is needed:</p>
<ul>
<li>It lets the FoundThis API associate requests with your store for quota and plan enforcement.</li>
<li>It is not used to access your WordPress admin or your customer data.</li>
</ul>
<p>When data is sent:<br />
– When you connect/register this site (to create an API key)<br />
– When optimization is enabled and the site receives front-end search requests<br />
– When you click the “Test Connection” button in the plugin settings</p>
<p>Purpose:<br />
– Improve search relevance by returning an optimized query</p>
<p>Privacy policy:<br />
– https://api.foundthis.us/privacy</p>
<p>Notes:<br />
– The API enforces plan gating and quota.<br />
– If the API is unavailable, the site search should continue to function.</p>
<h3>Developers</h3>
<p>Filters:<br />
– <code>foundthis_core_api_base_url</code> (string): Override the API base URL (advanced/dev use).<br />
– <code>foundthis_core_should_optimize_query</code> (bool, WP_Query): Return false to skip optimization for a given query.<br />
