• If you are trying to use Boolean operators, they must be ALL CAPS: ho hieu lang - ((thanh trung) OR (thanh cong)) cua nhung dung ((thanh tran) OR (thanh tra)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho hieu lang - ((thanh trung) or (thanh cong)) cua nhung dung ((thanh tran) OR (thanh tra)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho hieu lang - ((thanh trung) or (thanh cong)) cua nhung dung ((thanh tran) OR (thanh tra)) cau*.
