Adding text to product title in seach results (in suggestions dropdown box)

I’m trying to modify the Search Result title of the suggestions dropdown.
I tried the following hook, but it doesn’t seem to work on the suggestions box, is that correct? Is there a way to modify these titles?

add_filter( 'aws_title_search_result', 'my_aws_title_search_result', 10, 3 );
function my_aws_title_search_result( $title, $product_id, $product ) {
    $field = 'test-text';
    if ( $field ) {
        $title = $title . ' ' . $field;
    return $title;
