• Performing a fuzzy search may retrieve terms with similar spellings: theo ((hieu manh) or (chieu sang)) - hanh manh cua nhung ((huong manh) OR (duong manh)) toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((hieu manh) OR (chieu sang)) - hanh manh cua nhung ((huong manh) OR (duong manh)) toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((hieu manh) or (chieu sang)) - hanh manh cua nhung ((huong manh) OR (duong manh)) toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((hieu manh) or (chieu sang)) - hanh manh cua nhung ((huong manh) OR (duong manh)) toan cau*.
