I'm making a custom interface screen and want my technicians to be able to search requesters directly by Login Name.

SearchRequester.do?fromModule=WorkOrder&startsWith=X is fast, but only seems to search on names.

SearchN.do?fromModule=WorkOrder&searchText=X can find Login Name, but is much slower since it's searching all fields, I assume.

Is there any parameter for either of those functions to do the search I need?

Thanks!
