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