Adaptive RAG is a strategy for RAG that unites (1) query analysis with (2) active / self-corrective RAG.
In the paper, they report query analysis to route across:
- No Retrieval
- Single-shot RAG
- Iterative RAG
Let's build on this using LangGraph.
In our implementation, we will route between:
- Web search: for questions related to recent events
- Self-corrective RAG: for questions related to our index
