Awesome thanks for that Mikko – the new code I am using is above and after testing it does indeed work!

Or not – that seems to have yielded terrible results. Back to the drawing board.

Posting this here in the hopes it will help others – I think this is right, still in the process of testing:

add_filter('relevanssi_match', 'lower_title_weight');

function lower_title_weight($match) {
	$post_type = get_post_meta($match->doc);
	if (strlen($title) >= 15) {
		$match->weight = $match->weight / 2;
	}
	return $match;
}

Actually after thinking about this for a moment I guess the better option is to reduce the weight of long titles rather than increase the weight of short ones. This ensures that any relevant but long titles get pushed down, while non-relevant short titles don’t get an over bonus.

Still not sure where to begin implementing it but the reduction of weight on length would be more efficient.

As a simple work around could one add ’ = ‘ to the synonym list and turn on fuzzymatch?
