your page is using multiple criteria, it should only be using the one. key word criteria similar to what you had in the initial post. I think the problem you are having is actually a bug in the data assist search behavior. When you only have o
1 criteria, you cant change the separator from AND to OR in a key word search, that will need to be don't in the code.
in the code, you will see a line similar to:
$WADbSearch1->keywordComparison($KeyArr1,"".((isset($_POST["searchForm"]))?$_POST["searchForm"]:"") ."","AND","=",",%20","%20","%22","%22",0);
you will need to change it to:
$WADbSearch1->keywordComparison($KeyArr1,"".((isset($_POST["searchForm"]))?$_POST["searchForm"]:"") ."","OR","=",",%20","%20","%22","%22",0);
