Results sorting in last version

Yes, I too have the same issue.

In general, the latest version seems to have introduced more bugs than it fixed. I also wonder if the developer has ceased supporting this extension. There are outstanding requests over two weeks old. I understand that this is a free app but would be nice to have clarity if this is now time to move on.

Hi,

Apologies for the delayed response.

I haven’t changed anything significant in the search engine for over a year.
The plugin is at a early stage of development and it needs a lot of new features eg. fuzzy search, faster engine like inverted index, scoring and more.

In the next plugin release I’m going to add new algorithms to improve results sorting. If you can’t wait, try to paste following code into your functions.php. It should solve your problem.

add_filter('dgwt/wcas/search_results/output', 'dgwt_wcas_tmp_improve_relevance');

function dgwt_wcas_tmp_improve_relevance($output){

    if(empty($_REQUEST[ 's' ])){
        return $output;
    }

    $keyword = strtolower(sanitize_text_field( $_REQUEST[ 's' ] ));

    if(!empty($output[ 'suggestions' ])){
        $i = 0;
        foreach ($output[ 'suggestions' ] as $suggestion){

            $pname = strtolower($suggestion['value']);
            similar_text($keyword, $pname, $percent);

            $score = $percent;

            $pos = strpos($pname, $keyword);

            // Add score based on substring position
            if ($pos !== false) {
                $score += 50; // Bonus for contained substring

                // Bonus for substring position
                $posBonus = (100 - ($pos * 100) / strlen($pname)) / 2;
                $score    += $posBonus;
            }

            $output[ 'suggestions' ][$i]['score'] = $score;

            $i++;
        }
    }

    usort($output[ 'suggestions' ], 'dgwt_wcas_tmp_cmp_similarity');

    return $output;
}

function dgwt_wcas_tmp_cmp_similarity($a, $b)
{
    if ($a['score'] == $b['score']) {
        return 0;
    }

    return ($a['score'] < $b['score']) ? 1 : -1;
}

Thank You for a respond, this code really works fine.
