• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach o ((lang xa) OR (lang van)) hoi. hieu ((va chat) OR (vu cham)) luc va doan tap cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach o ((lang xa) OR (lang van)) hoi. hieu ((va chat) or (vu cham)) luc va doan tap cua te*".
