ADORE: Iterative Query Expansion with Retrieval-Grounded Relevance Feedback

Amin Bigdeli, Negar Arabzadeh, Radin Hamidi Rad +3

LLM-based query expansion improves retrieval by enriching the original query with additional context. Yet most methods remain generation-driven, producing plausible pseudo-document…
