Using lamma_index and qdrant, how do I query from a specific document_id from qdrant database?

Question

Using SimpleDirectoryReader we can index content of all files in a directory. And while queriying, it searches the entire collection in qdrant to find top-K similarities..

chat_engine = index.as_chat_engine(
service_context=service_context,
chat_mode=ChatMode.REACT, verbose=False)

chat_engine.chat("Who is wiki?")

I want to query, but from a specific document, even though I have indexed all documents in the directory. How do i do it?
