> It is very trappy that LatLonDocValuesField has stuff like newBoxQuery/newDistanceQuery.
> Users bring this up on the user list and are confused as to why the resulting queries
are slow.
> Here, we hurt the typical use case, to try to slightly speed up an esoteric one (sparse
stuff). Its a terrible tradeoff for the API.
> If we truly must have such slow methods in the public API, then they should have {{slow}}
in their name.
