• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((thu nang) OR (thu bang)) ma hoa. hieu ve cam ((xac va) OR (duc va)) dung tai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((thu nang) OR (thu bang)) ma hoa. hieu ve cam ((xac va) or (duc va)) dung tai cau treo".
• Adding a wildcard symbol may retrieve word variants: te sach ((thu nang) OR (thu bang)) ma hoa. hieu ve cam ((xac va) or (duc va)) dung tai cau treo*.
