By default WordPress only searches posts and pages. However, if you have a WooCommerce platform, it's extremely beneficial to allow users to search for products and product variations if you have them.

Step 1: Hook into pre_get_posts action

When you hook into the pre_get_posts action, you can easily modify the query used during the default WordPress search method. This allows you to adjust it so you can provide product and product_variation search functionality.

Add the following to an included PHP file in your WordPress theme or plugin:

add_action( 'pre_get_posts', 'ssu_search_woocommerce_products' );

function ssu_search_woocommerce_products( $query ) {
    if( ! is_admin() && is_search() && $query->is_main_query() ) {
        $query->set( 'post_type', array( 'post', 'page', 'product', 'product_variation' ) );

Before we modify the query, we check to see if 3 checks are true:

  1. The search is NOT coming from the admin side !is_admin()
  2. The query is the search query from a search form is_search()
  3. The query is the main query used to render the search template page $query->is_main_query()

Now we just adjust the post types searched to include product post type and product_variation post type. You will now get products and product variations in your search results.
