What suggestion was given in the forum thread to improve the LIKE comparison in the SQL query for better performance?

The suggestion given in the forum thread to improve the LIKE comparison in the SQL query for better performance was to avoid using wildcard characters at the beginning of the search string. This is because using wildcard characters at the beginning of the search string can prevent the query optimizer from using indexes efficiently. By placing the wildcard character at the end of the search string, the query optimizer can utilize indexes more effectively and improve query performance. 

$search_term = 'search_string%';

$query = "SELECT * FROM table_name WHERE column_name LIKE :search_term";
$stmt = $pdo->prepare($query);
$stmt->bindParam(':search_term', $search_term, PDO::PARAM_STR);
$stmt->execute();
