--------------------------------------------

Not sure why I originally used TermQuery in CheckIndex... I think switching to \
DocsEnum is fine...

> I noticed TestCustomNorms had the checkIndexOnClose disabled, but
> I think this is a real problem.
> If someone wants to use e.g. float[] norms, they should be able to run
> CheckIndex.
> CheckIndex is fine with validating any norm type, the problem is that it sometimes \
> creates an IndexSearcher and fires off TermQueries for some calculations. This \
> causes it to (wrongly) fail, because DefaultSimilarity expects single byte norms. I \
> don't think CheckIndex needs to use TermQuery here, we can do this differently so \
> it doesnt use IndexSearcher or TermQuery but just the postings apis.
