Modify this hook. You can retrieve get params and apply it to wp-query. Don't forget to sanitize params you receive from the request

function custom_search( $query_object )
{
    if( $query_object->is_search() ) {
        // Your wp query params
    }
}

add_action( 'parse_query', 'custom_search' );
