I get the following error while using secondstring:
"execute failed: need exactly one source in clusterMode"

my sourcecode:

import com.wcohen.ss.*;

SoftTokenFelligiSunter SFS = new SoftTokenFelligiSunter();

String o1 = "hallo";

String o2 = "hello";

double ergebnis = SFS.score(SFS.prepare(o1), SFS.prepare(o2));

Is there anywhere an example how to use SoftTokenFellegiSunter?

Best regards,

Philip
