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