• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((chieu xanh) or (chieu tinh)) - ((manh truong) OR (manh tuong)) cao nhung cong san toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu tinh)) - ((manh truong) OR (manh tuong)) cao nhung cong san toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu tinh)) - ((manh truong) OR (manh tuong)) cao nhung cong san toan cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu tinh)) - ((manh truong) OR (manh tuong)) cao nhung cong san toan cau*.
