[zhiyu-01]

Description

Search web for information.
When agent ask a question, google search can provide a list of urls which relative with the question, then using requests to get
each url and extract text. Split the text to small chunks and feed to chatgpt to get answer.

Notice: these functions require google api key you can find here https://developers.google.com/custom-search/v1/overview,
and search engine id you can find here https://cse.google.com/cse/all.

So, can anyone add these two key into the github actions, my pr need them to pass the test, thanks!
They look like this:

GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY")
SEARCH_ENGINE_ID = os.getenv("SEARCH_ENGINE_ID")

I have just noticed this new PR but before reviewing I think it would be better for you to do local cheks first before committing and pushing. It sends quite a lot of emails into my inboxes... And may I ask why you close this?
