Metadata and filtered retrieval
Metadata turns semantic search into scoped semantic search. Filtering by source, type, or date removes whole classes of wrong answer.
This lesson sits in Ingestion and Indexing, part of Retrieval-Augmented Generation from Scratch. It assumes what came before it and leads directly into the next lesson in the module.
In this lesson you will
- Attach source, type, and timestamp to every chunk
- Filter before ranking to cut the candidate set
- Use metadata to attribute answers back to a source
