Unlike other Teamraiser methods that take parameters event_type2 and event_type3 as search criteria, the "getTeamraisersByInfo" method makes use of Primary Event Type "event_type" as the only search criterion. Thus passing parameters event_type2 and event_type3 in the call here does not change the results set as the only search criterion being used is the search of Teamraisers is Primary Event Type "event_type".
