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