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