1. Is this request related to a challenge you're experiencing?

Currently the RAG retrieval is very base by using Vector store with similarity searching or full-text searching. Please add some advanced retrieval methods like "Sentence Window Retrieval" and "Auto-Merging Retrieval". It will improve the RAG performance metrics, like context relevance, answer relevance and Groundedness.

2. Describe the feature you'd like to see

please refer to the online course : https://learn.deeplearning.ai/courses/building-evaluating-advanced-rag/

3. How will this feature improve your workflow or experience?

Envolve some advanced RAG retrieval methods to improve RAG performance
