• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach lo ((vang ma) OR (tang ma)) hoi. hieu ve cham ((soc va) OR (hoc va)) danh di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach lo ((vang ma) OR (tang ma)) hoi. hieu ve cham ((soc va) or (hoc va)) danh di cua te*".
