             Summary: improve AtomicReader sugar apis
                 Key: LUCENE-4355
                 URL: https://issues.apache.org/jira/browse/LUCENE-4355
             Project: Lucene - Core
          Issue Type: Task
            Reporter: Robert Muir


I thought about this after looking @ LUCENE-4353:

AtomicReader has some sugar APIs that are over top of the flex apis (Fields, Terms, ...).
But these might be a little trappy/confusing compared to 3.x.

# I dont think we need AtomicReader.termDocsEnum(Bits, ...) and .termPositionsEnum(Bits, ...).
I also don't think we need variants that take flags here. We should simplify these to be less
trappy. I think we only need (String, BytesRef) here.
# This means you need to use the flex apis for more expert usage: but we make this a bit too
hard since we only let you get a Terms (which you must null check, then call .iterator() on,
then seekExact, ...). I think it could help if we balanced this out by adding some sugar like
AtomicReader.termsEnum? 3.x had a method that let you get a 'positioned termsenum'.
