The method further preferably includes assigning each of the plurality of biometric data groups to a plurality of biometric searching engines so that each of the plurality of biometric data groups is assigned to only one of the plurality of biometric searching engines. An apparatus for expandable biometric searching preferably includes a plurality of biometric data groups each of which includes a plurality of biometric records having at least one biometric index and biometric data and a full range of biometric indexes. Each of the plurality of biometric data groups is preferably uncorrelated to the biometric indexes. An apparatus also preferably includes a plurality of biometric searching engines.
