Indexing post slugs

By default Relevanssi does not index the post slug. It is, however, an easy thing to fix using the relevanssi_content_to_index filter hook. This function will read the post slug, replace the hyphens with spaces (so that indexing-post-slugs becomes “indexing post slugs”) and add the slug to the post content. Just add this function to your theme functions.php and rebuild the index to see it in effect.

add_filter( 'relevanssi_content_to_index', 'rlv_index_slug', 10, 2 );
function rlv_index_slug( $content, $post ) {
    $slug_with_spaces = str_replace( '-', ' ', $post->post_name );
    return $content . ' ' . $slug_with_spaces;
}
