Multi-tenant dense retrieval systems increasingly employ shared compressed indexes where individual tenants adapt embeddings via fine-tuning (e.g., LoRA). While query-side projection adapters bridge the resulting embedding mismatch, a critical design choice remains for the optional reranking stage: should distances be...
