Is this a llama index thing or langchain

The post asks whether the issue is related to LlamaIndex or Langchain. A community member confirms that it is a Langchain-related issue, and mentions that the Langchain Discord channel is not very responsive, so they decided to ask here. Other community members provide some helpful information, such as the lack of a dedicated retriever for Qdrant in Langchain, and suggest using the similarity_search function instead of get_relevant_documents. They also share links to the Langchain repository, which lists all the available retrievers.
