• If you are trying to use Boolean operators, they must be ALL CAPS: ((((thi hieu) OR (thien chien))) OR (theo chu)) sang - anh dang luan hang nong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: ((((thi hieu) or (thien chien))) or (theo chu)) sang - anh dang luan hang nong dan toan cau*.
