• If you are trying to use Boolean operators, they must be ALL CAPS: ((thao bo) OR (theo bo)) manh - anh mang ((suat thong) OR (cua thuong)) cong dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thao bo) OR (theo bo)) manh - anh mang ((suat thong) or (cua thuong)) cong dan toan cao".
• Adding a wildcard symbol may retrieve word variants: ((thao bo) OR (theo bo)) manh - anh mang ((suat thong) or (cua thuong)) cong dan toan cao*.
