Nevertheless, straight inserting prolonged and sometimes irrelevant retrieved paperwork can disrupt the reasoning course of and scale back coherence because it incorporates verbose and tangential info.

3. Search-o1

The Search-o1 framework enhances the agentic RAG mechanism by introducing a Purpose-in-Paperwork module. This module refines retrieved paperwork into concise reasoning steps that seamlessly combine exterior data whereas preserving the logical development of the reasoning chain. By factoring within the present search question, retrieved paperwork, and the evolving reasoning chain, it generates coherent and interconnected steps. This iterative method continues till a conclusive reply is derived.
