Review Comment:
That's fair. As you've noticed, the ngram tokenizer has nothing to do with
the root cause: it is only there to multiply the number of postings in docs,
which in turns increases the probability that a consistent failure case arises.
But of course the same can be achieved by simply crafting the index that way
explicitly, and I agree that extra code and dependency just adds noise and gets
in the way of understanding what the test is about.
