• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - ((thanh cung) OR (thanh cuong)) chua khong ((cong ty) OR (cong san)) than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - ((thanh cung) OR (thanh cuong)) chua khong ((cong ty) or (cong san)) than cau".
