Searches for strings and regular expression patterns in files. The classification rule assigns the property only if all expressions that you specify are found. Strings are not case sensitive unless you choose the StringCaseSensitive or RegularExpression types.

Important: Complex regular expressions can reduce classification speed and consume large amounts of memory. See MSDN for more information about regular expressions.
