• Performing a fuzzy search may retrieve terms with similar spellings: thuat san y nang ma hoi. hieu ve cao duc van anh ve ((cua tre) or (((cuu tre) OR (cau treo))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san y nang ma hoi. hieu ve cao duc van anh ve ((cua tre) OR (((cuu tre) OR (cau treo)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san y nang ma hoi. hieu ve cao duc van anh ve ((cua tre) or (((cuu tre) OR (cau treo))))".
• Adding a wildcard symbol may retrieve word variants: thuat san y nang ma hoi. hieu ve cao duc van anh ve ((cua tre) or (((cuu tre) OR (cau treo))))*.
