• Type: Bug

Description

Steps to reproduce the problem:
Start two Solr instances (may use the example configuration)
add some documents to both instances
execute a query like: http://localhost:8983/solr/select?shards=localhost:8983/solr,localhost:8984/solr&q=(ipod%20OR%20display)&*fl=score*

Expected result:
List of scores or at least an exception saying that this request is not supported (may not make too much sense to do fl=score, but a descriptive exception can help debug the problem)

Getting:

• relates to: SOLR-3214 If you use multiple fl entries rather than a comma separated list, all but the first entry can be ignored if you are using distributed search.
