The knowledge base we created has limited information. Use web search to broaden the scope of the answer_questions_about_topics tool.

Fill in any <CODE_BLOCK_N> placeholders and run the cells under the 🦹 Use web search to get information section in the notebook to use DuckDuckGo search if the information required to answer a particular question is not present in the knowledge base.

    result = search.run(query)
    context = [Document(page_content=result)]
