To whom it may concern,
The wikipedia article about CouchDB says "Aggregate

filters <http://en.wikipedia.org/wiki/Filter_%28software%29> are
computed in
parallel as in MapReduce <http://en.wikipedia.org/wiki/MapReduce>,
rather
than at query time (although queries may introduce new aggregate
functions,
which execute on the existing documents in parallel)."
Specifically what
kind of aggregations is this referring to if it is accurate at all.
I guess the refer to the reduce part of out Map/Reduce system that lets
you create your own kinds of aggregations.
Thanks,
