• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty hang xa hoi. ((hieu ve) OR (hieu va)) cham ((thuc va) OR (tuc xa)) danh te cua te~.
• Adding a wildcard symbol may retrieve word variants: tu sach ty hang xa hoi. ((hieu ve) or (hieu va)) cham ((thuc va) or (tuc xa)) danh te cua te*.
