Key Parameters
:The
follow
10
parameter can be used to specify the userids
of 5,000 users as a comma separated list.
Rate Limit
: Rate limiting works differently in the Streaming API. In each
connection an application is allowed to submit up to 5,000 Twitter userids. Only
public Tweets published by the user can be captured using this API.

Collecting Search Results
Search on Twitter is facilitated through the use of parameters. Acceptable parameter
values for search include keywords, hashtags, phrases, geographic regions, and
usernames or userids. Twitter search is quite powerful and is accessible by both
the REST and the Streaming APIs. There are certain subtle differences when using
each API to retrieve search results.
2.5.1
REST API
Twitter provides the
search/tweets
API to facilitate searching the Tweets. The search
API takes words as queries and multiple queries can be combined as a comma
separated list. Tweets from the previous 10 days can be searched using this API.
