Stay organized with collections Save and categorize content based on your preferences.

A QueryFieldFilterConstraint is used to narrow the set of documents returned by a Firestore query by filtering on one or more document fields. QueryFieldFilterConstraints are created by invoking where() and can then be passed to query() to create a new query instance that also contains this QueryFieldFilterConstraint.
