Researchers have developed Navigation-Informed Embeddings (NIE), a novel method to adapt dense retrieval models using traces from agentic search workflows. This approach leverages query, retrieval, and stopping traces to fine-tune deployed models without requiring new relevance labels, synthetic queries, or LLM judgments. By treating stopping documents as positive examples and incorporating preceding path documents, NIE significantly improves retrieval performance, boosting Recall@20 by up to 5.8 points and nDCG@10 by 1.9 points on benchmarks like BEIR HotpotQA.
