Handling Small Chunks in Docling HybridChunker

[harskuma]

Hi everyone,

I’m currently using Docling’s HybridChunker for chunking PDF documents. I understand that it follows hierarchical chunking, which generally works well. However, I’ve noticed that some chunks end up being too small, especially for PDFs.

To address this, I’ve already tried:

Setting max_tokens to control chunk size.
merge_peers=True
Despite these adjustments, I’m still seeing some very small chunks in the output.

Is there any other approach or parameter tweak that could help ensure more consistent chunk sizes, while still maintaining the hierarchical structure?

Would appreciate any suggestions or insights!

@harskuma did you find a workaround ?
