Interesting, thanks. Actually I can't split the tuple values up -- the requirement is to see those terms occur together in the same tuple, not just for the same document (there is a difference in this case). So, I'll try expanding the max_term count to see if that helps; otherwise I'll have to rethink the solution. -- Posted via http://www.ruby-forum.com/. _______________________________________________ Ferret-talk mailing list [email protected] http://rubyforge.org/mailman/listinfo/ferret-talk
