Snippet Library
Search snippets for WordPress
Snippets that improve WordPress search: search custom fields and post types, exclude pages, redirect single results and highlight matching words. For content-heavy sites where visitors need to find things quickly.
Exclude a Category From Search Results
Keeps posts from the categories you choose, such as internal updates or sponsored posts, out of the site search results.
Match Category and Tag Names in Search
Makes the site search also return posts whose categories or tags match the search words, so searching "recipes" finds everything filed under Recipes.
Product Search Box Above the Shop
Places the WooCommerce product search box above the product grid on the shop and product category pages.
Search Within the Current Category
On category pages, adds an "Only in [category]" checkbox to the search form and Search block, ticked by default, so visitors can search just that section.
