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