For configuring the number of returned links in SearxNG, you can use the num_results parameter within your search configuration. This parameter allows you to specify the desired number of search results, with a range from 1 to a maximum of 20 results. Adjusting this parameter will directly affect the number of results SearxNG returns for your searches.

While the documentation does not explicitly detail configuring the number of results for Google searches within your setup, it's common for search APIs, including Google's, to offer a way to control the number of search results via API request parameters.

For specific implementation details and to adjust these settings, you might want to look into the searxng_search.py and searxng_search.yaml files within the Dify repository. These files contain configurations and parameters related to search operations, including how to set the number of results returned by the search tools.

I am testing searxng and also found that there is no limit parameter, but only the pageno parameter, The reason is that searxng is an integration platform, it just gets a page of data from other search engines and then integrates it, so there is no parameter such as limit set.

• Official documentation: Search API.
• Related issue: Return number of result pages in the API

If we directly put the results returned by searxng into llm, there will be too much content and more tokens will be consumed, so we can configure a step to truncate the content in workflow, for example:

The code can be referenced, only use first 5 results:

def main(arg1: dict) -> dict:
    output = ""
    i = 0
    for item in arg1:
        if i > 5:
            break
        title = item.get("title", "")
        url = item.get("url", "")
        content = item.get("content", "")
        output += f"标题: {title}\n"
        output += f"链接: {url}\n"
        output += f"内容: {content}\n\n"
        i += 1
    
    return {
        "result": output,
    }

As for the google api, I didn't test it, I'm not sure what the problem is.
