Hi Carsten,

It doesn't sound as though an inverted index is really what you want to be querying here,
if I'm reading you right.  You want to get the payloads for spans at a specific position,
but you don't particularly care about the actual term at that position?  You might find that
BinaryDocValues are a better fit here, but it's difficult to tell without knowing what your
actual use case is.

 Is that the sort of thing you're looking for?
