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