• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach kem) OR (sach y)) nang xa hoi. ((hieu ve) OR (hieu va)) cam tuc ban thanh va su tien.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach kem) or (sach y)) nang xa hoi. ((hieu ve) OR (hieu va)) cam tuc ban thanh va su tien".
• Adding a wildcard symbol may retrieve word variants: su ((sach kem) or (sach y)) nang xa hoi. ((hieu ve) OR (hieu va)) cam tuc ban thanh va su tien*.
