• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (theo tieu)) xanh - thanh tung cua nhung ((cong van) OR (cong vang)) ban cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (theo tieu)) xanh - thanh tung cua nhung ((cong van) OR (cong vang)) ban cau~".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (theo tieu)) xanh - thanh tung cua nhung ((cong van) OR (cong vang)) ban cau*.
