Report #55171

[frontier] Naive RAG returning irrelevant chunks because of lexical or embedding ambiguity in user queries

Replace direct vector search with a two-step Semantic Routing architecture: first use a fast, fine-tuned classifier or LLM to route the query to a specific domain/tool, then perform targeted retrieval only within that domain's curated index.

Journey Context:
Throwing everything into a single vector database creates noise; embeddings for 'bank' \(river\) and 'bank' \(finance\) collide, leading to cross-domain contamination. Semantic routing partitions the problem space. It adds a small latency overhead for the routing step but drastically improves precision by constraining the retrieval space and applying domain-specific pre-processing rules.
