# Enhance Search Index Chunking in Data 360 by Using Code Extension

Improve how Data 360 search indexes handle unstructured data by using a custom Python chunking function. Write, test, package, and deploy your function by using code extension.

**Where:** This change applies to Data 360 Enterprise, Performance, Unlimited, and Developer editions. Not available in Government Cloud.

**When:** This feature is available in June 2026.

**Why:** Data 360 includes built-in chunking strategies, but they don't always suit every content pattern or retrieval goal. For more control, for example, keeping related sections together in complex PDFs, author a custom Python chunking function by using code extension and use it as the chunking strategy in your search index.

**How:** To customize chunking behavior to your specific business requirements, select your function as the Chunking Strategy in search index Advanced Setup.
