This bug has been fixed in 3.1 and trunk. This can happen when there was some sort of exception during the sub-request. Go look at the logs on each server (or execute the request on each server w/o the "shards" param) to see what the exception is. -Yonik http://www.lucenerevolution.org -- Lucene/Solr User Conference, May 25-26, San Francisco
