docs.getMaxScore is null inside writeSolrDocumentList when sorting using shards
and returning output as JSON
------------------------------------------------------------------------------------------------------------
Key: SOLR-626
URL: https://issues.apache.org/jira/browse/SOLR-626
Project: Solr
Issue Type: Bug
Components: search
Affects Versions: 1.3
Environment: Tested on both Linux and OSX running latest 1.3 build
Reporter: ian connor
When issuing a query to many shards or even just one:
http://localhost:8983/solr/select?sort=some_date+desc&indent=on&hl.fl=&q=solr&rows=10&fl=*%2Cscore&qt=standard&wt=ruby&explainOther=&hl.fl=&shards=localhost:8983/solr
It returns:
java.lang.NullPointerException

org.apache.solr.request.JSONWriter.writeSolrDocumentList(JSONResponseWriter.java:528)

I tried to swap out the call to writeLong from:
writeFloat(null,docs.getMaxScore());
to:
writeFloat(null,0);
and it then works without bringing back the max_score. However, I am not sure
why the score is coming back null here. If you return the results in XML it
also works so the problem seems limited to JSON and Ruby.
