Passing a null fieldname to MemoryFields#terms in MemoryIndex throws a NPE
--------------------------------------------------------------------------

                 Key: LUCENE-3831
                 URL: https://issues.apache.org/jira/browse/LUCENE-3831
             Project: Lucene - Java
          Issue Type: Bug
          Components: core/index
    Affects Versions: 4.0
            Reporter: Alan Woodward
            Priority: Minor


I found this when querying a MemoryIndex using a RegexpQuery wrapped by a SpanMultiTermQueryWrapper.
 If the regexp doesn't match anything in the index, it gets rewritten to an empty SpanOrQuery
with a null field value, which then triggers the NPE.
