Hey Peter To sort these on the client side is no problem. But we have a problem using pivot facet queries. If we set the facet.limit=-1 the load can cause OutOfMemoryExceptions on the server side. Thanks again for the patch. I will keep an eye on it.

On the server-side, you can look at https://issues.apache.org/jira/browse/SOLR-1672 - please note this is an old patch for 1.4, so this won't work on 4.x - but it can give an idea of how/where to do the sorting on the server-side, if you want to go down that road.
