Another question not so simple to answer: When embedding these TermPositions
into the whole process, how would this work with MultiTermQuery? The current
algorithm is simple: The TrieRangeTermEnum simply enumerates the possible
terms from the index and MTQ creates the BitSet or a BooleanQuery of
TermQueries. How to do this with positions? In both cases there need
specialities (the TermEnum must return that the actual term is a
payload/position one and must filter using TermPositions). For the filter
its then easy, the TermQueries added to BooleanQuery in the other case must
also use the payloads. Questions & more questions.

I tend to release TrieRange with 2.9 without Positions/Payloads.
