Abstract
A method comprises receiving a first cryptographic token for one search term and a second cryptographic token is generated using the one search term and at least another search term. A first search is conducted using the first cryptographic token to generate a first result set, and the second cryptographic token is used for computing a subset of results of the first result set.
