Query Rewriting and Retrieval Quality

By the end of this module you can improve retrieval by fixing the query rather than the model, and measure whether a rewrite actually retrieved better documents.

Units

1. Unit 04.00: The question the user typed is rarely the query you need
2. Unit 04.01: Expanding, narrowing, and splitting a question
3. Unit 04.02: Rewriting for filters rather than for wording
4. Unit 04.03: Measuring whether the rewrite actually helped
5. Unit 04.04: When rewriting makes retrieval worse
