• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu tinh - anh hang ((cua thong) OR (cua khong)) ((cong tan) OR (cong san)) tran cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - anh hang ((cua thong) OR (cua khong)) ((cong tan) or (cong san)) tran cao~".
• Adding a wildcard symbol may retrieve word variants: theo chieu tinh - anh hang ((cua thong) OR (cua khong)) ((cong tan) or (cong san)) tran cao*.
