• Performing a fuzzy search may retrieve terms with similar spellings: tu dan ((ky tang) or (ky dang)) van hoe. hieu ve cam ((cuu san) OR (cua san)) danh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu dan ((ky tang) OR (ky dang)) van hoe. hieu ve cam ((cuu san) OR (cua san)) danh vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu dan ((ky tang) or (ky dang)) van hoe. hieu ve cam ((cuu san) OR (cua san)) danh vi cuu tre*".
