As long as one replica for each shard is "active", you should be able to query the collection.
You an also index to the collection and it'll all "just work", when the replicas that are not active become active they'll get the updates and catch up to the leader. This process may take quite some time so it is probably best, if you have a choice, to turn indexing on after all the replicas are up and running. This is not a requirement, however.
