QueryNonFilterConstraint

QueryNonFilterConstraint is a helper union type that represents QueryConstraints which are used to narrow or order the set of documents, but that do not explicitly filter on a document field. QueryNonFilterConstraints are created by invoking orderBy, {@link (startAt:1)}, {@link (startAfter:1)}, {@link (endBefore:1)}, {@link (endAt:1)}, limit or limitToLast and can then be passed to {@link (query:1)} to create a new query instance that also contains the QueryConstraint.
