tlloancy Catalog Search for WooCommerce is a small WooCommerce product search for shops that do not need a heavy search engine.
It builds a compact inverted index (title, parent and variation SKUs, product category) and answers from a REST route. No external service, no jQuery.
The overlay is a real veil: the shop stays visible under a semi-transparent backdrop. A close control sits in the panel. Hidden and catalog-only products stay out of the index, same as WooCommerce search.
Search UI
What it does not do
Insert the Catalog Search for WooCommerce block on the shop / product archive template. Settings live under Settings Catalog Search for WooCommerce.
Optional search-term stats (off by default) store normalized queries and counters in a dedicated table. The visitor cookie is a random UUID for deduplication only.
