I suggest adding a new operator that does regular expression matching for string/text type filters.

Currently, string or text filters such as Subject, Description, and Notes use SQL's LIKE to find objects that match the given search string. Needless to say, support for regular expressions allows for more flexible searches. Since recent versions of MySQL, PostgreSQL, and SQLite allow regular expressions in the WHERE clause, I think it is possible to implement the new regexp operator.
