Hi Zhe,
The Search API can only return approx 1800 per query. Creating a radius that
covers the whole earth would be counter productive.
Instead you may wish to use the Streaming API. Using this API you can say
that you want all Geocoded Tweets from around the world. If you do that any
Tweet which includes geo information will be Streaming to you in real time
-- up to the allowed sample percentage.
You can read more about this API on our developer resources site:
http://dev.twitter.com/pages/streaming_api
in particular:
