• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ma hoi. ((hieu ve) OR (hieu va)) cham ((luc va) OR (duc va)) hanh lai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ma hoi. ((hieu ve) or (hieu va)) cham ((luc va) OR (duc va)) hanh lai cua te*".
