• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang x hoi. hieu ((ve cam) OR (ve cham)) trung va ((hang dien) OR (nhan dien)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang x hoi. hieu ((ve cam) OR (ve cham)) trung va ((hang dien) or (nhan dien)) cua te".
• Adding a wildcard symbol may retrieve word variants: su sach y nang x hoi. hieu ((ve cam) OR (ve cham)) trung va ((hang dien) or (nhan dien)) cua te*.
