hi @atolto-pirla !
I am sorry, I believe I mistaken the classes 
Actually, this is the deprecated one: WeaviateHybridSearchRetriever — 🦜🔗 LangChain documentation
This is considering that Weaviate python V3 client is definitely deprecated So all integrations based on v3 client is now obsolete / deprecated.
Based on that recipe, let me know what you are attempting on doing, and I can try helping!
Thanks!
