- 01 Conversational Query Rewriting Turning a context-dependent follow-up into a self-contained query, which is what lets a stateless retriever serve a stateful conversation.
- 02 Parsing Queries into Structured Filters Turning a free-text query into attribute constraints and residual text that a structured index can execute exactly, from CRF query tagging to schema-constrained LLM parsing, and why negation is the case that makes parsing worth its cost.
- 03 Query Expansion and Pseudo-Relevance Feedback Adding terms to a query to bridge vocabulary mismatch, and the drift failure that occurs when the terms are harvested from results that were wrong to begin with.
