Unable to filter using metadata in the new version

[kiran-bal]

Iam using R2R version 3.6.1 with ollama - llama3.1 model. I have added a pdf document to the R2R using the custom ingestion_mode. When iam using the rag stream iam unable the filter not getting applied. Please see the below code and let me know if this is not the right approach for metadata filtering in rag stream.

search_settings = {
    "use_semantic_search": True,
    "filters": {"metadata.doc_type": {"$eq": "video"}}
}


result =r2r_client.retrieval.rag(
query=query,
task_prompt=R2R_DOC_CHAT_TEMPLATE,
search_settings=search_settings,
rag_generation_config={
    "stream": True
}
)
