what is the traditional way of sorting search results?

order by case
    when price between @priceMin and @priceMax 
        and location = @location then 1
    when price between @priceMin and @priceMax 
        and district_id = @districtid then 2
    when no_of_bedrooms = @no_of_bedrooms 
        and districtid = @districtid then 3
    when price between @priceMin and @priceMax 
        and no_of_bedrooms = @no_of_bedrooms 
        and property_area = @property_area and districtid <> @districtid then 4
    else 5
end, price desc

$json = json_decode($wikisearchlist);
$results = $json[1];

$first = array_shift($results);

$filtered = array_filter($results, function($result) {
    return strpos($result, '(soundtrack)') !== false
        || strpos($result, '(Download album)') !== false;
});

array_unshift($filtered, $first);
