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