portal search

hello again everyone was great the last time i needed help so here we go. i have a portal based on a table tracing various district attorneys and the trial they handle. in some cases there are two da's on a single case(lead-assisting). this info is entered by a value list containing an ada_id and ada_lastname. the problem is if i search for the da whose name is in the second portal row(assisting ada) the search results only shows me the result of the first portal role(lead ada). any ideas on how to search on the various portal rows to get the desired result. thanks in advance
