• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) xanh - hanh manh ((cua khong) OR (hua khong)) xuong van ban cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chieu)) xanh - hanh manh ((cua khong) OR (hua khong)) xuong van ban cau".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chieu)) xanh - hanh manh ((cua khong) OR (hua khong)) xuong van ban cau*.
