We provide an example implementation for this filter which is available as a plugin at https://github.com/itthinx/wps-indexer-filter-test – this example will add metadata based on the test_meta key to the product’s content being indexed.

The following example will include product metadata for series, part number and manufacturer. The corresponding meta keys are held in the $fields variable:

add_filter(
    'woocommerce_product_search_indexer_filter_content',
    'example_indexer_filter_content',
    10,
    3
);

function example_indexer_filter_content( $content, $context, $post_id ) {
    if ( $context === 'post_content' ) {
        $fields = array( 'series', 'part_number', 'manufacturer' );
        $product = wc_get_product( $post_id );
        $meta_values = array();
        foreach ( $fields as $meta_key ) {
            $meta_value = $product->get_meta( $meta_key );
            if ( !empty( $meta_value ) && is_string( $meta_value ) ) {
                $meta_values[] = $meta_value;
            }
        }
        if ( count( $meta_values ) > 0 ) {
            $content .= ' ' . implode( ' ', $meta_values );
        }
    }
    return $content;
}

The woocommerce_product_search_indexer_filter_content filter can be used together with desired product metadata to include any desired additional information for products. Once the products are again indexed, the search engine will retrieve results based on the added information. This also works with plugins such as Advanced Custom Fields who rely on WordPress’ metadata related to posts.

Please note that you need to re-index so the search engine will find the added data.
