Needs a docstring. It looks like there's some sorting happening, perhaps because the generated query isn't deterministic?

The query is deterministic, but if I remove this, I had to change many tests because some commutative operators like OR and AND. Since both queries mean the same, the test should accept them as equal under commutative operations.
