Hi,
here's a small patch that makes the summaries non-random. Currently the use
of hashCode() leads to quasi-random results, i.e. you can get a different
summary when you reload a result page. That's a bit confusing. With this
patch you'll always get the same summary.
(I actually sent this to Michael Cafarella some months ago, but I think it
was lost/forgotten back then).
Regards
Daniel
