• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (theo chu)) xanh - hanh hang va dung cong ((dan than) OR (dan chan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (theo chu)) xanh - hanh hang va dung cong ((dan than) OR (dan chan)) cau".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (theo chu)) xanh - hanh hang va dung cong ((dan than) OR (dan chan)) cau*.
