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