* `=`: Select labels that are exactly equal to the provided string.
* `!=`: Select labels that are not equal to the provided string.
* `=~`: Select labels that regex-match the provided string (or substring).
* `!~`: Select labels that do not regex-match the provided string (or substring).
* `=~`: Select labels that regex-match the provided string.
* `!~`: Select labels that do not regex-match the provided string.
