woocommerce_product_filter_cache_max_entries │ filter-hook │ WC 10.8.0

Maximum number of cache entries (not unique filter combos).

Each unique query-vars combo can produce up to 5 entries (price, stock, rating, attribute, taxonomy), so the effective cap on unique combos is roughly max_entries / 5.

When the limit is reached, new entries are skipped until the cache is next invalidated. Set to 0 to disable the cap.

Usage

add_filter( 'woocommerce_product_filter_cache_max_entries', 'wp_kama_woocommerce_product_filter_cache_max_entries_filter' );
