How to search for brands?

Don’t read it if you use one of the supported brand plugins.

At the very beginning, consider whether you handle brands in your WooCommerce via a plugin or you have a custom solution. If you use a plugin, check our list of compatible brand plugins. If your plugin is on the list, you can stop to read this article.

Let’s go!

This tutorial shows how to integrate any brand solution based on custom taxonomy with FiboSearch. As a result, the users will be able to search for products by brands and see matching brands in autocomplete including brand’s thumbnails.

Assume that the name of custom taxonomy is product_brand.

Step 1 – Register your custom taxonomy in FiboSearch

add_filter( 'dgwt/wcas/indexer/taxonomies', function ( $taxonomies ) {
	$taxonomies[] = array(
		'taxonomy'      => 'product_brand1',
		'labels'        => array(
			'name'          => 'Brands',
			'singular_name' => 'Brand',
		'image_support' => true,

	return $taxonomies;
} );

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

Turning on this opinion allows searching for products by brand terms. It means if you type e.g. “bike” in search, you will see all products assigned to the brand “Nike”.

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

Step 3 – Turn on “Show brands” in the FiboSearch settings

Turning on this opinion allows displaying matching brand terms in autocomplete search as suggestions.

Go to WooCommerce -> FiboSearch -> Autocomplete (tab). The new checkbox called “Show brands” should appear under the section “Non-products in autocomplete”. Check it and save the settings.

Step 4 (optional) – Support for brand image

Images aren’t supported in WordPress as part of custom taxonomies. To handle images you have to use a custom solution.

First, turn on images for brands in the FiboSearch options.

By default, FiboSearch will be looking for the value thumbnail_id stored in the term_meta table in a database. In this example, we assumed that brand image is handled in a different way by Advanced Custom Fields. Let it be the ACF field brand_image_url assigned to product_brand taxonomy. Learn more about how to do it in ACF.

Set field type as “Image” and a return format as “Image URL” Then you will be able to use the following snippet to pass the brand image URL to the FiboSearch indexer.

add_filter( 'dgwt/wcas/term/thumbnail_src', function ( $src, $term_id, $size, $term ) {
	if ( $term->getTaxonomy() !== 'product_brand' ) {
		return $src;

	return (string) get_field( 'brand_image_url', $term->getTermObject() );
}, 10, 4 );

Step 5 – Rebuild the search index

After saving the settings, the search index should start rebuilding automatically. Go to WooCommerce -> FiboSearch -> Indexer (tab), observe the status and wait for finishing.

Step 6 – Let’s see if it works

Check if the brand and related products show up in an autocomplete. The results should look like this:
