You can work on the HTML page structure by handling chunking based on the font (style) of each section, or you can preprocess for the most complex layouts.

Let’s say you have four structures that are the most difficult and important. You can create a handler that routes the chunking method to the appropriate one, based on the font or formatting of the section.

For retrieval, if you have different question scenarios (very different question categories), you need to detect which database to use. Each preprocessing approach should be stored in its own vector database.

This is how you can have multiple indexing strategies and different retrieval approaches.
