Problem/Motivation

Usecase:
There are three nodes with the following titles: foo, bar, drupal. Requirement: Create a view that lists nodes that does not have title foo or bar.

Using views string filter you can't create a SQL expression like "some_field NOT IN ('foo', 'bar')", as a workaround when searching a multiple value string in a string Regular Expression operation can be chosen but it's hard to implement a reverse search for regex because the regex is done on SQL level which is limited according to https://dev.mysql.com/doc/refman/5.7/en/regexp.html

POSIX regexes don't support using the question mark ? as a non-greedy (lazy) modifier to the star and plus quantifiers like PCRE (Perl Compatible Regular Expressions). This means you can't use +? and *?
