Do I need to re-index after changing settings?

Yes, you must delete your current index file and re-run the indexing command to regenerate embeddings using your new chunking parameters.

How does chunk size affect search results?

Smaller chunks offer higher precision for specific lines but less context, while larger chunks provide more context at the risk of including irrelevant code noise.

Which settings are best for verbose languages like Java?

For verbose languages, a larger chunk size (e.g., 768 tokens) and higher overlap are recommended to ensure full methods and class structures are captured.

What is code chunking in GrepAI?

Chunking is the process of splitting large source files into smaller, overlapping segments so they can be effectively processed by embedding models for semantic search.

Why should I use overlap in my index configuration?

Overlap ensures that context at the boundaries of chunks is preserved, preventing the AI from missing related logic that happens to span across a split point.

Optimizes semantic code search by configuring precise file splitting and embedding parameters within GrepAI.

GrepAI Indexing provides a specialized framework for managing how source code is partitioned into searchable chunks for vector embeddings. By fine-tuning parameters like chunk size and overlap, developers can balance search precision with logical context, ensuring that AI agents retrieve complete, relevant code snippets rather than fragmented results. This skill is essential for optimizing search performance across diverse codebases, offering tailored strategies for everything from verbose monoliths to concise microservices.
