Yokozuna inconsistent search results

Hi Magnus,

You are right, there was a Solr indexing issue:

2016-03-01 09:00:17,640 [ERROR] <qtp2109588399-1460>@SolrException.java:109
org.apache.solr.common.SolrException: Invalid Date String:'Invalid date'

However I'm struggling to find the object that causes this, the error
message doesn't contain the object id and the bucket is really huge. Can
you suggest the way to find the object that causes Solr exception?

Thanks!
