> Does a *:* query with no sorting work? Well, this is interesting. Leaving q= as it was, but removing the sort, makes the whole thing work.
And if you were thinking of asking whether the sort field is a date, the answer is yes, it's an indexed and stored DateField. It's also on the list of fields whose values I am requesting with fl=. So I guess this is likely to be the date that is somehow turning up in the ClassCastException. Great suggestion. Thanks, Cody. Now I'm wondering if anyone familiar with the Field Collapsing code can see a possible vector for a bug, given this fleshing out of the bug conditions. -- Bryan > -----Original Message----- > From: Young, Cody [mailto:cody.yo...@move.com] > Sent: Thursday, June 21, 2012 11:04 AM > To: solr-user@lucene.apache.org > Subject: RE: Exception using distributed field-collapsing > > No, I believe it was a different exception, just brainstorming.
