-------------------------------------
Here is another seed from another test, find the same failure:

I will dig in a little bit more. I ran into a similar problem before with
SpanNot, maybe this is a similar one, that happened like this:
# sub-approximation is positioned on docid 1
# we call sub.advance(2) and it returns 3
# <we do other processing and then move forward to doc 3, but we never called
matches()>
So in that case we needed some state to be able to lazily call matches() once
and only once when actually needed. SpanNot uses this state for its sub, which
records the last document we called matches() for and the return value that
matches() had.
{code}
int lastApproxDoc = -1;
boolean lastApproxResult = false;
{code}
Maybe this one is a similar thing, i will look more.
