A php search engine that only shows results that match entire serch string

Question

I have set up a dreamweaver search engine through php and a fulltext search (WHERE MATCH (....) AGAINST (...). However, when someone inputs more than one word into the search form, the search engine churns out results that only have one of those words. How do I get it to only show results that have all the search string words inside? (or, at least, how do I get those results to show up at the top?)
I have seen some advice (here) that uses php code to process the search query, divide up the words, and place a BOOLEAN '+' between each of the words. By doing this, the search engine will only show results that fully match all the terms.
My problem is that I do not know how to put this code into my Dreamweaver-created code.
My dreamweaver created code:
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;   
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  return $theValue;
$form_rsSearch = "-1";
if (isset($_get['search'])) {
  $form_rsSearch = $_get['search'];
mysql_select_db($database_dataConnect, $dataConnect);
$query_rsSearch = sprintf("SELECT title, content FROM encyclopedia WHERE MATCH (title, content) AGAINST (%s)", GetSQLValueString($form_rsSearch, "text"));
$rsSearch = mysql_query($query_rsSearch, $dataConnect) or die(mysql_error());
$row_rsSearch = mysql_fetch_assoc($rsSearch);
$totalRows_rsSearch = mysql_num_rows($rsSearch);
$input_rsSearchResults = "-1";
if (isset($_GET['search'])) {
  $input_rsSearchResults = $_GET['search'];
mysql_select_db($database_EMdataConnect, $dataConnect);
$query_rsSearchResults = sprintf("SELECT title, content FROM encyclopedia WHERE MATCH(title, content) AGAINST(%s)", GetSQLValueString($input_rsSearchResults, "text"));
$rsSearchResults = mysql_query($query_rsSearchResults, $dataConnect) or die(mysql_error());
$row_rsSearchResults = mysql_fetch_assoc($rsSearchResults);
?>
and the code the website (link above) gives is:
function search(String $search_string) {
     //strip Boolean search characters out of search string
     $search_string = string_replace($search_string,"+","");
     $search_string = string_replace($search_string,"-","");
     $search_string = string_replace($search_string,"*","");
     //split the search string up into an array of words
     Array $tokenized_search = split($search_string, " ");
     //init an empty final search string
     String $processed_search = "";
     //for each word in the search, wrap it
     //with an + and * character and then append
     //it to the processed_search variable
     foreach($tokenized_search as $token) {
          $processed_search+="+"+$token+"* ";
     //build the sql for the query and query the DB
     String $db_query = "select id, description
          from product_descriptions
          where MATCH(description)
          AGAINST ('"+$processed_search+"' IN BOOLEAN MODE)";
     Array results = execute_database_query($db_query);
     return results;
If anyone can instruct me on the correct way to go about this, I would be very much obliged.
Thank you,

Don't use the Search bar, type the address in the Location bar.
