WPXERO

<p><strong>FalcoSearch was formerly known as Xero Finder.</strong> Your settings, shortcodes, and developer hooks continue to work unchanged after the rename.</p>
<p>FalcoSearch is a falcon-fast live search and product-filter plugin built around WooCommerce. Shoppers type once and see matching products — with images, price, stock, and rating — before they finish the word. Refine results in place with instant filters for category, price, rating, on-sale, bestseller, and stock status. No page reloads. No plugin bloat. No jQuery.</p>
<h4>Why WooCommerce stores choose FalcoSearch</h4>
<ul>
<li><strong>Instant product results as you type</strong> — title, SKU, price, rating, stock, on-sale, bestseller, newest.</li>
<li><strong>In-place product filters</strong> — category, price range, rating, stock, sale; combine freely.</li>
<li><strong>Lower bounce on product searches</strong> — debounced AJAX, server-side caching, conditional asset loading.</li>
<li><strong>No theme rewrite required</strong> — drop in the <code>[xerosf_icon]</code> or <code>[xerosf_input]</code> shortcode anywhere, or use the floating modal.</li>
<li><strong>Works alongside your existing theme search</strong> — FalcoSearch enhances the native WordPress search input on focus.</li>

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.
