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