Summary

Cloud Firestore now supports not-equal and not-in queries, allowing developers to retrieve documents whose field values differ from a specified value or are excluded from a list of values, such as projects not marked “completed” or “dropped.” These queries do not return documents where the queried field is absent. They also follow existing inequality-query limitations, including restrictions on applying not-equal conditions to multiple fields or sorting by a different field, while combinations with equality filters on another field may require a composite index. The functionality is available in the iOS, Android, Web, Node.js, and Java SDKs, with C++ and additional server-library support planned.
