• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly vang ((ma hoi) OR (mai hoi)). hieu van cam ((luc va) OR (duc va)) hanh dong cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly vang ((ma hoi) or (mai hoi)). hieu van cam ((luc va) OR (duc va)) hanh dong cua te*".
