 * surrounding a phrase in quotes (`"`) matches on that exact phrase. For example, `"foo bar"` matches scenes with `foo bar` in the title. Quotes may also be used to escape the keywords and symbols. For example, `foo "-bar"` will match scenes with `foo` and `-bar`.
 * quoted phrases may be used with the or and not operators. For example, `"foo bar" or baz -"xyz zyx"` will match scenes with `foo bar` *or* `baz`, and exclude those with `xyz zyx`.
 * `or` keywords or symbols at the start or end of a line will be treated literally. That is, `or foo` will match scenes with `or` and `foo`.
