Overview
Chunk size decides what a match can even mean. Too small and passages lose context; too large and the relevant sentence gets drowned.
In this lesson you will:
- Split on structure rather than a fixed character count
- Use overlap to avoid cutting an idea in half
- Keep each chunk understandable on its own
Pro Tip
Use caching and revalidation wisely to ensure your app stays fast and data remains fresh without unnecessary requests.
