search with or when calling table_list.php

Hi,
I'd like to know if, when calling:
http://server/app/table_to_search_list.php?a=search&value=1&SearchFor=1104&SearchOption=Contains&SearchField=hsg
which works fine with one value, it is possible to somehow combine values in the searchString with or:
resulting in something like "hsg IN('1104','1105')" in the generated sqlString?
thanks
