• _max_fetch_count*deadline 必须小于等于 request duration
  
• 必须考虑到请求次数的限额，在个人负担允许范围内使用。

Warning: The user ids in the Search API are different from those in the REST API (about the two APIs). This defect is being tracked by Issue 214. This means that the to_user_id and from_user_id field vary from the actualy user id on Twitter.com. Applications will have to perform a screen name-based lookup with the users/show method to get the correct user id if necessary.
