I'd like to conclude my previous post in a less elaborate way: I need to

a) combine two WildcardQueries so that I can still use
SpanMultiTermQueryWrapper to generate a SpanQuery.

b) apply a filter to a WildcardQuery so that the WildcardQuery's results
are reduced before converting it to a SpanQuery using
SpanMultiTermQueryWrapper.

Answer b) seems intuitively the way to go there, but I don't quite find
the correct path there because the filter does not work as intended (see
my previous post).
Answer a) does not seem feasible here either because
SpanMultiTermQueryWrapper requires a MultiTermQuery, but not a BooleanQuery.

Any hints on that?
Best,
Carsten
