Firestore database document 'startsWith' query

[Bishwajyoti Roy]

Is it possible to query on a firestore database collection to show documents that start with a specific string?

[Michael Lehenbauer]

Hi Bishwajyoti,

You can essentially do this with a carefully-crafted range query...  E.g. to find documents with ID's that begin with 'foo', I believe you could do:

      collection

        .where(firebase.firestore.FieldPath.documentId(), '>=', 'foo')

        .where(firebase.firestore.FieldPath.documentId(), '<', 'fop')

        .get()

        .then(querySnapshot => { ... });

Hope this helps,

-Michael
