READ count

[klaszlo8207]

1, If I have a collection with 50000 items with geo data, and I use this library to filter out the distance with 10km from me, than it will cost 50000 READ count?

2, Can I use lets say: limit 50? (and it will cost 50 READ?)

3, Can I use getDocuments instead of stream?

4, Can I use collection('items').where('datetime', isGreaterThan: datetime) or not?
