> In the CartesianShapeFilterBuilder, there is logic that determines the "best fit" tier
to create the Filter against.  However, it does not account for which fields actually exist
in the index when doing so.  For instance, if you index tiers 1 through 10, but then choose
a very small radius to restrict the space to, it will likely choose a tier like 15 or 16,
which of course does not exist.
