Purpose of this application is find duplicate records,

I have arround 60K records for contact and 60K records for lead.

I tried to SOSL/SOQL query join between contact and lead but its not possible as there is no any link between contact-lead object.

In SOSL able to get all records but there is issue fot get all records into one query because SOSL has 2000 max limit.

Appericiate for any sample code or any ideas!!!
Thanks in Advance!
