CAMI: Cost-Aware Agent-Guided Multi-Indexing for Semantic Retrieval

arXiv:2606.28365v1 Announce Type: cross Abstract: RAG ingestion pipelines frequently augment search corpus index with semantic enrichment indices (e.g., synthetic queries or summaries generated from corpus chunks) that are subsequently queried alongside the base index to improve retrieval via better alignment between document representations and user intent. While these supplementary representations substantially improve retrieval quality, they introduce a computational bottleneck: the configuration space of enrichment types and generator models is combinatorial, and the cost of exhaustive ind

Why this matters
Why now

The proliferation of complex RAG pipelines in AI agents and applications necessitates more efficient and cost-aware indexing strategies.

Why it’s important

This development addresses a critical bottleneck in deploying scalable and performant semantic retrieval systems, directly impacting the economic viability and practical application of advanced AI.

What changes

The trade-off between retrieval quality and the computational cost of semantic enrichment indices becomes more manageable through intelligent agent-guided multi-indexing.
