Post Title Only?

  • Because Relevanssi overrides the search to include all custom fields, I can’t work out how to specifically filter to only the post title. I’ve created a filter on search for my music library website. What this allows is to do is the following, assuming my search query is: 1999?

    If I don’t filter to anything it produces all posts that has an association with 1999. 

    If I select year it only shows me posts where the value of the custom field ‘year’ is 1999 (all songs from 1999).

    If I select album it only shows me posts where the value of the custom field ‘album’ is 1999 (like Prince’s album). 

    So now, if I select Song Title, I’d expect only 1 result, and that should be the song 1999 by Prince. But that’s not happening. Song title is NOT a custom field. It’s the title of the post. How can I filter to it?

    Happy to share code if need be. Thank you!

    This code snippet makes Relevanssi only match titles:

    add_filter( 'relevanssi_match', function( $match ) {
    if ( $match->title < 1 ) {
        $match->weight = 0;
    }
    return $match;
} );

    Now just make this trigger based on your song title filter – I suppose there’s a query variable you can check?

    Hello and thank you for sharing this filter to only match titles, it works fine for me.

    Now i need it to apply only in a specific page and i’m stuck…
    I tried this without success, the filter doesn’t seem to apply to the search result once the condition is set: 

    add_filter( 'relevanssi_match', function( $match ) {
	if ( is_page( 'search-products' ) ) {
		if ( $match->title < 1 ) {
			$match->weight = 0;
		} 
		return $match;
	}
} );

    To be noted: the search field is a WP Gridbuilder facet with Relevanssi enabled as the search engine.
    Not sure it makes a difference given the filter above works without the condition… but i’m far from mastering PHP.

    Any hint is welcome!

    Is it an AJAX search? If you’re doing an AJAX search, you’re not on the page, so is_page() won’t work. You need a different condition to check. You can access the WP_Query object with global $wp_query; – perhaps the query variables in $wp_query->query_vars[] have something useful you can use as a condition? Another option is checking the parameters in $_REQUEST. I can’t be more specific, as I don’t know any of the details, but you can do this:

    add_filter( 'relevanssi_match', function( $match ) {
  global $wp_query;
  error_log( print_r( $wp_query->query_vars ) );
  return $match;
} );

    Do a general search on your site and a search with your WP Gridbuilder facet, and compare the output that’s in the server error log. Can you spot a difference you can use as a condition?

    Also, return $match; needs to be outside the conditional, otherwise the search will break.

    Thanks a lot for the leads @msaari, now i will explore. ??

    Yes Ajax search is enabled on this WP Gridbuilder facet, probably a reason why the conditional fails by targeting a specific page as you mentioned.
    And yes, there’s an URL variable that could be used (generated by WPGB).
