• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuat sach)) ty sang ma hoi. ((hieu ve) OR (hieu va)) cam loc va hanh giau cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (thuat sach)) ty sang ma hoi. ((hieu ve) or (hieu va)) cam loc va hanh giau cua tre*.
