FalcoSearch is a WordPress plugin that adds instant live search and AJAX product filters to a WooCommerce store or any WordPress site. Visitors see matching products and posts while they type, then narrow a shop or archive page by category, price, rating, availability and more — without a page reload.

It combines two tools that are usually separate plugins:

Live search — a search box that shows results as the visitor types.
Filter builder — a drag-and-drop editor for product and post filters, with SEO-friendly filter URLs.

FalcoSearch was formerly called Xero Finder. Settings, shortcodes and developer hooks are unchanged.

What you can do with FalcoSearch

Add an instant product search to a WooCommerce store, with prices and sale badges in the results
Add faceted product filters — category, price, color, size, brand, rating, stock — beside your shop grid
Let shoppers combine filters and see results update without a page reload
Give filtered pages clean, indexable URLs such as /shop/color-blue/
Filter and search blog posts or any custom post type, not only products
See what visitors search for, and which searches find nothing

Set up in minutes

Activate. On a store, products are searchable straight away.
Search: press Ctrl + / (Cmd + / on Mac) on your site, or add the [xerosf_icon] shortcode.
Filters: click New Filter Set Set up shop filters for me. FalcoSearch builds filters from your own categories, prices and product attributes and shows them on your shop pages.

No code, no template edits. Everything can be changed afterwards in a visual editor.

Live search

A search window opens over the page and lists results as the visitor types.

Instant results with thumbnail, highlighted match, post type and date
WooCommerce details in each product result: price, sale badge, out-of-stock badge
Four ways to open it: a shortcode button or input, your theme’s existing search field, Ctrl + / (Cmd + / on Mac), or a triple-click
Three layouts: modal, full screen, top bar
Choose what is searched: titles only, titles and excerpts, or titles, excerpts and content
Search more fields: ACF fields and Yoast SEO / Rank Math focus keywords and descriptions
Smarter matching: synonyms, word-by-word fallback when a phrase finds nothing, and operators such as "exact phrase" and -exclude
Voice search in browsers that support speech recognition (Chrome, Edge, Safari)
Quick-search suggestions you define, shown before the visitor types
Favorites and recent searches, kept in the visitor’s own browser
Keyboard friendly: arrow keys move through results, Enter searches, Escape closes
Cross-site search: include results from other sites running FalcoSearch

Product and post filters

Build a set of filters in the editor, then show it on your shop, category, search or archive pages.

12 filter types: checkbox list, radio buttons, dropdown, buttons, color and image swatches, range slider, min / max inputs, star rating, availability toggles (in stock, on sale, featured, downloadable, backorder), author, date range, category tree
One-click setup: a ready-made filter set built from your store’s categories, prices and attributes
Add filters by what they filter — Price, Category, Brand, Color, Rating — already configured
Visual editor: drag to reorder, rename, switch how a filter is displayed, see a live preview
Store currency is used on price filters automatically
AJAX filtering: results, counts, active-filter chips and pagination update in place
Live counts: each option shows how many results it would give
Sidebar layout: on WooCommerce archives a vertical filter set sits beside the product grid; horizontal and off-canvas layouts are also available
Mobile drawer: on phones the filters open full screen from a floating “Filters” button
Instant or “Apply” mode, sorting dropdown, collapsible groups, “show more”, search within long lists
Placement: automatic on matching archives, or with a shortcode, a block or an Elementor widget
Works without JavaScript for checkbox, radio, dropdown, rating, date and min / max filters
Any post type: works for blog posts and custom post types, not only products

SEO for filtered pages

Clean filter URLs such as /shop/color-blue/brand-acer/, with redirects to one canonical order
Title, H1 and meta description templates per filter set
Indexing control: choose how many taxonomy filters deep a page may be indexed; pages filtered by price, stock, rating, date or sort order are noindex,follow
Canonical tags and an XML sitemap provider for indexable filter pages
Works with Yoast SEO and Rank Math, and on its own when neither is installed

Search analytics

Total searches, unique terms and average results per search
Zero-result searches — what visitors looked for and did not find
Top keywords and search volume over time
CSV export and a configurable retention period

Also included

Related posts shortcode, with optional automatic placement on single posts
404 rescue: redirect a missing URL to the closest matching post
