on the products results page, change the following line of code:
php:
$WADbSearch1->keywordComparison($KeyArr1,"".((isset($_GET["S_ProductName"]))?$_GET["S_ProductName"]:"") ."","WHERE","Includes",",%20","%20","%22","%22",0);
to:
php:
$WADbSearch1->keywordComparison($KeyArr1,"".((isset($_GET["S_ProductName"]))?$_GET["S_ProductName"]:"") ."","WHERE","Includes","%20",",%20","%22","%22",0);
this will change it so that " " (space) is used as the AND separator and ", " (comma space) is used as the OR separator.
