The purpose of the ^ and the $ is to define the beginning and the end of a word: http://il2.php.net/regex I also tried str_replace( $noiseArray, " ", $searchQuery) but that was replacing the insides of words as well. And with the addition of the individual letters, that emptied the entire $searchQuery string! A typical value of $searchQuery could be "What is php?" or "What is open source".
