Build a bounded query
Add where clauses, ordering, and a limit while the project, database, and collection remain visible.
From query idea to working query
Build and troubleshoot Firestore queries
Compose filters, ordering, and limits visually, catch obvious conflicts, and use Firebase’s exact link when a composite index is missing.
Catch obvious conflicts early
Client-side preflight flags mismatched inequality ordering and likely composite-index requirements before or alongside the request.
Use the verified Firebase index link
When Firestore returns a missing-index error, verify the Firebase Console host and project before opening the exact generated definition.
Scope and limits
Know what this workflow does.
- Only Firestore can confirm whether a specific index exists or is required.
- Cengal does not create or deploy indexes.
- Google Cloud IAM permissions, billed reads, and Firestore query limits still apply.
