    $keywords = preg_split('/\s+/', strtolower(trim($search)));
    $searchClauses = [];

    foreach ($keywords as $word) {
        $searchClauses[] = "(LOWER(org_name) LIKE ? OR LOWER(country) LIKE ? OR LOWER(org_extra_info) LIKE ? OR LOWER(org_category) LIKE ? OR LOWER(location) LIKE ?)";
        // Push the same word 5 times for 5 fields
        for ($i = 0; $i < 5; $i++) {
            $params[] = "%$word%";
            $types .= "s";
        }
