Optimizing Search Results

So you achive your needs please use following code snippet

add_filter( 'aws_search_query_array', 'my_aws_search_query_array' );
function my_aws_search_query_array( $query ) {
    $relevance = "( case when ( term_source = 'title' ) then 300 else 0 end ) +";
    $relevance .= "( case when ( term_source = 'tag' ) then 250 else 0 end ) +";
    $query['relevance'] = preg_replace( '/\(SUM\([\s\S]*?\([\s\S]*?case[\s\S]*?end[\s\S]*?\)[\s\S]*?\+/i', '$0' . $relevance, $query['relevance'] );
    return $query;
}

You need to add it somewhere outside the plugins folder. For example, inside functions.php file of your theme or use some plugin for adding code snippets.

Also after adding this code you will need to go to the plugin settings page and click the ‘Clear cache’ button.

This code will add more relevance to tags and title sources.

It did help to some degree, but it’s still not at the level I want it to be. Is it possible to add relevance to an attribute named “collection”?

Yes, it is possible. Please modify previous code. Just replace it with this new one and clear the cache.

add_filter( 'aws_search_query_array', 'my_aws_search_query_array' );
function my_aws_search_query_array( $query ) {
    $relevance = "( case when ( term_source = 'title' ) then 300 else 0 end ) +";
    $relevance .= "( case when ( term_source = 'tag' ) then 250 else 0 end ) +";
    $relevance .= "( case when ( term_source = 'tag' AND term LIKE '%collection%' ) then 800 else 0 end ) + ";
    $relevance .= "( case when ( term_source = 'category' AND term LIKE '%collection%' ) then 800 else 0 end ) + ";
    $relevance .= "( case when ( term_source = 'attr_pa_collection' ) then 800 else 0 end ) + ";
    $query['relevance'] = preg_replace( '/\(SUM\([\s\S]*?\([\s\S]*?case[\s\S]*?end[\s\S]*?\)[\s\S]*?\+/i', '$0' . $relevance, $query['relevance'] );
    return $query;
}

Is there any way to force the search for golden AND rose AND necklace? Instead of golden OR rose OR necklace?

It is possible only with pro plugin version. It has feature to use AND search logic instead of OR. Read here more.
