• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sac ky) OR (cac ky)) nang ((ma hoi) OR (mai hoi)). hieu ve cao suc van nhan viec cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sac ky) or (cac ky)) nang ((ma hoi) OR (mai hoi)). hieu ve cao suc van nhan viec cua te".
