this URL

but it only gives me tweets that are tweeted i开发者_JS百科n last 7 days.

I have found one... by using MGTwitter i am able to retrieve it... Thanks

If you need collect Tweets older than 7 days you can't do it with Twitter's API, but I think you can do it using web-scraping (the tweets can easily be scraped with the Python module BeautifulSoup ; but please if any one know the disadvantage of this method tell us!

I don't think the twitter search API allows you to go back any further. If you add the until parameter you can see that if you go back more than a week it returns a 404.
