Chunking strategies

Chunk size decides what a match can even mean. Too small and passages lose context; too large and the relevant sentence gets drowned.

What this lesson covers

• 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
