<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.
