> WANDScorer has special logic to deal with corner cases when the sum of the
> maximum scores of sub queries is either 0 or +Infty, but both code and tests
> have backwards logic regarding this special case, doing +1 instead of -1 and
> vice-versa.
> This leads to a failed assertion in the case when the sum of the scores of
> the sub queries overflows, which typically happens if one of the clauses has
> a default implementation that returns MAX_VALUE if it cannot reason about max
> scores.
