• Performing a fuzzy search may retrieve terms with similar spellings: theo hieu lang - ((hanh tang) OR (hanh mang)) cua dong ((huong manh) or (tung manh)) toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo hieu lang - ((hanh tang) OR (hanh mang)) cua dong ((huong manh) OR (tung manh)) toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo hieu lang - ((hanh tang) OR (hanh mang)) cua dong ((huong manh) or (tung manh)) toan cao*".
