[twitter-dev] How to get MOre than 1500 tweets when searched in Search API

[basha]

I submitted my request with 100 RPP and 15 pages. then i am getting
1500 tweets. but when I tried using since_id 1312101395 along with RPP
and Pages I am getting only latest 1500 tweets. How can I get tweets
which were present before the latest 1500 tweets
(1501,1502,1503,..............).
Overall i want a mechanism where i can get all the tweets irrespective
of the number greater or less than 1500. please tell me the mechanism.
i am codeing the above in java.
