• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((thien anh) OR (thien danh)) - thanh truong cao ((trong cong) OR (hang cong)) dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thien anh) OR (thien danh)) - thanh truong cao ((trong cong) or (hang cong)) dan toan cao".
