Description

Bug Summary:
During web search functionality within OpenWebui version 0.5.4 using DuckDuckGo as the search engine, a critical error arises when attempting to extract relevant data from the search results. The error persists at the _text_extract_json() stage and is attributed to a ValueError: subsection not found exception.

Reproduction Details
