While is not an error the library should allow me to specify the collection name right ?

@DavidNorena could you share a snippet of code to show how to reproduce the error?

[David Noreña Perez]

When you init the memory with Qdrant there is no way to change the default collection which I believe is something needs improvement

We were not using the default collection in qdrant, so If you dont specify when searching it will throw the warning ...

I believe there should be a way to init the default collection on configuration right ?

[Devis Lucato]

I agree it would be nice configuring more details about Qdrant, like the default collection, a prefix, field names etc, and we'd welcome PRs in that sense.

With regard to the logs, those are only warnings, and the connector creates the collection automatically when missing.
