> we use this getFieldNames api in segmentmerger if we merge something that isn't a SegmentReader
(e.g. FilterIndexReader)
> it looks to me that if you use a FilterIndexReader, call addIndexes(Reader...) the docvalues
will be simply dropped.
> I dont think its enough to just note that the field has docvalues either right? We need
to also set the type

we need to have a 
> FieldOption for each ValueType so that we correctly update the type.
> But looking at FI.update/setDocValues, it doesn't look like we 'type-promote' here anyway?
