Search can be done by Titles, Attributes, Tags, Categories, Description, Short Description, SKUs and even Meta fields.

Today’s customers expect to find what they want fast. If they can’t, they bounce — and that bounce rate kills your SEO performance. A powerful product search plugin not only gives your users a smoother experience, it also keeps them engaged longer, lowers bounce rates, and increases your chances of conversion. All of these directly impact your organic rankings and paid campaign success.
Pros: 
✅ Boosts Conversions: When shoppers can instantly find products, they buy faster. 
✅ SEO Wins: Better user engagement = longer sessions = better Google rankings. 
✅ Smarter Merchandising: Highlight high-margin, trending, or seasonal products easily. 
✅ Better UX on Mobile: Optimized search ensures mobile users stay and shop. 
✅ Data-Driven Marketing: Top plugins provide search analytics, giving you insights into what your customers really want.
Cons: 
⚠️ Potential Site Speed Issues: Cheap or bloated plugins can slow your site down — choose wisely. 
⚠️ Setup Time: Proper configuration is key to getting the full SEO benefits. 
⚠️ Premium Pricing: The free versions are good, but serious stores will eventually need a paid upgrade.

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.
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>.
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.

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.
