- The filter matches using both the URL and the title, case-insensitively.
`test`will simply search for test.`!test`will exclude anything containing test.`test, !b`will include anything containing test that does not contain b.`test, b`will search for anything containing test or b. There is no way to do 'and' instead of 'or'.`https://workplace, https://stackoverflow, !test`will show only posts from workplace and stackoverflow, that do not have 'test' in the title.`!https://workplace,!https://stackoverflow`will show everything except workplace and stackoverflow.- You cannot use escape characters.
- Exclamation points that are not at the start, do not negate the search. E.g.
`no!`is not a negative filter. - A good way to match sites is by matching just a little bit around the site name. E.g. https://security.stackexchange.com/question/x can be matched using
`/security.`and mathoverflow using`/mathoverflow.`. - A set of filters that I like is this.
