Starting from versions 2.4.0 (Premium) and 4.3.0 (Free), Relevanssi doesn’t index posts that have been marked “noindex” in the Yoast SEO settings (“Allow search engines to show this Post in search results?”). If the “noindex” setting is in the default value or set to explicit “yes”, Relevanssi indexes the post.
If you want Relevanssi to disregard the Yoast SEO “noindex” setting, you can adjust that from the advanced indexing settings.
Using Yoast SEO title instead of post title
This little function in your functions.php will make Relevanssi use the Yoast SEO title instead of post title when indexing posts:
add_filter( 'relevanssi_post_title_before_tokenize', 'rlv_use_yoast_title', 10, 2 );
function rlv_use_yoast_title( $title, $post ) {
return get_post_meta( $post->ID, '_yoast_wpseo_title', true );
}
I added Relevanssi because my default search engine would only search posts (not articles or pages). Relevanssi does the same thing – my results are only from posts; no pages or articles. How do I tell it to search the whole site? Yes, I did check the boxes for these three items when I created the index.
Relevanssi would search the whole site. If you use the Admin search (Dashboard > Admin search), does that return all kinds of posts? It’s possible your theme is restricting the search results to posts. Does your theme have any settings that could affect this?
That works! (Dashboard > Admin search) How do I tell my search bar to perform this way? I’m very much a novice in this area.
That depends on your theme, and since your theme is a premium theme, I can’t tell. If you have access to theme support, you could ask them.
