Yes they have the same field name.
Can we use the default posIncr? If I want to create an IndexWriter w/o an
Analyzer, why should I be forced to do new IndexWriter(new SimpleAnalyzer()
/* for example */ ...), when the analyzer will never be used?
It is an edge case though which I can easily reproduce, but not sure how
important it is to fix it (the fix should be simple though).
