Michael McCandless commented on LUCENE-3831:
--------------------------------------------

Hmm I don't think the Fields.terms API should be expected to accept null (eg I don't know if the other codecs will NPE).

I'd rather fix span queries to not pass the null field.  Is this happening in SpanTermQuery.getSpans()?

> 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.
