How to query a subcollection?

[dgilperez]

Hi!

I am trying to query a subcollection, but I can't find any documentation nor make the current functions work. Is this supported by the project?

• If I try to add the subcollection route to the parent_path (path/documents/collection_name/doc_id/subcollection_name), I get a Invalid value at 'structured_query' 400 error message.
• If I try to add that to the query, then another 400 appears: Collection id _full_qualified_name_ is invalid because it contains \\\"/\\\"

Thanks!
