Open ranges in OR and unknown clauses are not adjusted. Use :cls:`UnknownOperationResolver`
to make sure that unknown operations are resolved first.

Ranges with none of the bounds set are left unadjusted. Additionally, the ranges must be
direct siblings of the same parent. Ranges such as ``[foo TO *]^2 AND [* TO bar]^2`` are
therefore not merged (though ``([foo TO *] AND [* TO bar])^2`` would).

are therefore not merged (though ``([foo TO *] AND [* TO bar])^2`` would).

Also not that it does not check ranges bound ordering
so that you might end-up with incoherent ranges like [* TO 3] AND [4 TO *] -> [4 TO 3]
