Description

FalcoSearch was formerly known as Xero Finder. Your settings, shortcodes, and developer hooks continue to work unchanged after the rename.

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.

Why WooCommerce stores choose FalcoSearch

  • Instant product results as you type — title, SKU, price, rating, stock, on-sale, bestseller, newest.
  • In-place product filters — category, price range, rating, stock, sale; combine freely.
  • Lower bounce on product searches — debounced AJAX, server-side caching, conditional asset loading.
  • No theme rewrite required — drop in the [xerosf_icon] or [xerosf_input] shortcode anywhere, or use the floating modal.
  • Works alongside your existing theme search — FalcoSearch enhances the native WordPress search input on focus.

}, 10, 2 );

add_filter( 'xerosf_results', function ( $results, $post_ids, $term, $args ) {

Support

For help, please open a thread on the WordPress.org support forum:
https://wordpress.org/support/plugin/wpxero-search-filter/

  1. Upload the wpxero-search-filter folder to /wp-content/plugins/, or install from the WordPress plugin directory.
  2. Activate the plugin from Plugins Installed Plugins.
  3. Configure the search at FalcoSearch in the admin sidebar.
  4. View search analytics at FalcoSearch Analytics.
  5. Optionally, drop [xerosf_icon text="Search"] or [xerosf_input placeholder="Search…"] into a page, post, or widget.
Does FalcoSearch work with WooCommerce?

Yes. FalcoSearch is built around WooCommerce. It searches product title and SKU, exposes filters for category, price range, rating, stock status, on-sale, bestseller, and newest, and renders product results with the featured image, price, and rating in the live modal.

I was using “Xero Finder”. Is this the same plugin?

Yes. FalcoSearch is the new name for Xero Finder (also previously branded as WPXERO Search Filter). The plugin slug, text domain, settings, shortcodes, and developer hooks are all unchanged — updating to v1.1.0 will not break your site.

Will my existing settings and shortcodes keep working after the rename?

Yes. The option key (wpxero_search_settings), shortcodes ([xerosf_icon], [xerosf_input]), and filter hooks (xerosf_weights, xerosf_results, xerosf_analytics_retention_days) are unchanged in v1.1.0 and beyond.

Is FalcoSearch multilingual?

Yes. The plugin is fully translatable (text domain: wpxero-search-filter) and ships a .pot file. It is compatible with WPML and Polylang.

Does the plugin require jQuery?

No. The frontend is built in vanilla JavaScript and does not enqueue jQuery.

Does FalcoSearch include a dark mode?

Yes. Type /dark in the search modal to switch to dark mode, or /light to switch back. The theme is also configurable from the admin settings page.

How do I add the search bar to my theme?

Use one of the bundled shortcodes — [xerosf_icon] for a magnifying-glass icon that opens the modal, or [xerosf_input] for an inline input. Both also work in blocks, widgets, and PHP via do_shortcode(). Alternatively, leave the floating modal triggers (Ctrl+/, triple-click, or input focus) enabled and FalcoSearch will hook into your existing theme search input on focus.

How do I view search analytics?

Open FalcoSearch Analytics in the admin sidebar. You can see total searches, zero-result queries, top keywords, search volume over time, and export the raw data as CSV.

Can I customise how results are ranked?

Yes. Hook the xerosf_weights filter to change the relevance weights per search mode, and xerosf_results to post-process the result set after the engine has built it.

Does FalcoSearch send my visitors’ data to an external service?

No. FalcoSearch does not make external HTTP calls and does not track visitors. The analytics dashboard is stored locally in your own WordPress database.

How do I uninstall and delete all data?

Deactivating leaves your settings in place so a re-install picks them up where you left off. To wipe everything, enable Remove all data on uninstall in the settings page first, then delete the plugin from the Plugins screen — this removes the options and analytics tables on uninstall. (Setting introduced in v1.1.0; default off.)
