A chunk from “Chapter 5: Security” should include that context, not just raw text. 2️⃣ Implement Sliding Windows 👉 Create overlapping chunks (overlap 10-20% of tokens) so context doesn’t break at arbitrary boundaries. This prevents losing information split across chunk borders. 3️⃣ Hierarchical Chunking �
