How to search for products by custom taxonomy?

The solution requires custom PHP snippets. To apply, you can both:

1. Open the functions.php file in your child theme and add the code at the end
2. Or install the Code Snippets plugin and apply this code as a snippet.

The following example is taken from our mockup store, The Bookstore Online. Book authors are custom taxonomies with the name book_author

Step 1 – Register your custom taxonomy in FiboSearch 

add_filter( 'dgwt/wcas/indexer/taxonomies', function ( $taxonomies ) {
	$taxonomies[] = 'book_author';

	return $taxonomies;
} );

Step 2 – Turn on “Search in authors” in the FiboSearch settings 

Go to WooCommerce -> FiboSearch -> Search config (tab). The new checkbox called “Search in authors” should appear under the section “Products search scope”. Check it and save the settings.

Step 3 – Rebuild the search index

After saving the settings, the search index should start rebuilding automatically.

Go to WooCommerce → FiboSearch → Indexer (tab) and rebuild the search index. Wait for this process to finish.

Step 4 – Let’s see if it works

Check if you can search products by terms from the custom taxonomy.
