Hi,

I would that each user will get all the Docs excepts those includes his userId.

How can i do that?

also can you please explain why the where() query is not available? I can use only whereEqualTo, whereGreaterThan, whereLessThan etc.

Thanks in advance,

Kobi.d

Hello,

As documented here, you can use in and array-contains to create an OR query, or you can simply query for both conditions and aggregate client side. See also aggregation queries.

Hi Kobi.d,

Right now Firestore does not support "not equal" queries although that is something we have on our roadmap. We have whereEqualTo and the other methods in order to help you find which types of queries we support. It's much more type safe than .where('field', '==', 'value') for Java developers.
