Answer 2

Tibor Santa that's not what I'm looking for, I need to get the document ID by knowing the fields. What you send is the opposite: by knowing the document ID, get the fields.

Answer 3

In that case you will need to write a query. An attribute may not be able to uniquely identify a single element from your collection, so a query like that may yield multiple results.
