• Performing a fuzzy search may retrieve terms with similar spellings: tuyen tap ((((cac chu) or (cac khu))) or (((cac che) OR (cac he)))) đe co ban va y thuc cong cong~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tuyen tap ((((cac chu) OR (cac khu))) OR (((cac che) OR (cac he)))) đe co ban va y thuc cong cong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tuyen tap ((((cac chu) or (cac khu))) or (((cac che) OR (cac he)))) đe co ban va y thuc cong cong".
• Adding a wildcard symbol may retrieve word variants: tuyen tap ((((cac chu) or (cac khu))) or (((cac che) OR (cac he)))) đe co ban va y thuc cong cong*.
