🐛 Bug Detection

Potential issues:

• scrapegraphai/utils/research_web.py
  The error is occurring in the test_google_search function. The test is expecting exactly 2 results from the search_on_web function, but it's receiving 4 results instead. This mismatch is causing the assertion to fail.
  Let's break down the problem:

1. The test is calling search_on_web("test query", search_engine="duckduckgo", max_results=2).
2. The function is expected to return 2 results (as specified by max_results=2).
3. However, the function is actually returning 4 results.
   This suggests that the search_on_web function is not correctly limiting the number of results to the specified max_results parameter when using the DuckDuckGo search engine.
   The issue is likely in the implementation of the DuckDuckGo search in the search_on_web function. Specifically, in this part of the code:

if search_engine == "duckduckgo":
    research = DuckDuckGoSearchResults(max_results=max_results)
    res = research.run(query)
    results = re.findall(r"https?://[^\s,\]]+", res)

The DuckDuckGoSearchResults object is created with the correct max_results, but the results are then extracted using a regex pattern. This regex extraction might not be respecting the max_results limit.
To fix this, the code should explicitly limit the number of results after the regex extraction:

results = re.findall(r"https?://[^\s,\]]+", res)[:max_results]

This change would ensure that no more than max_results URLs are returned, regardless of how many are found by the regex.
