David Smiley commented on SOLR-6797:
------------------------------------
Oh, I forgot something key. maxDistErr needs to reflect the same units as the
new distanceUnits you have here. Same with SpatialArgs.distErr.
Example/default schema should reflect 1 meter's worth and not depend on
degrees. You might want to add a little Units class for this -- we've got 3
values.
> Add score=degrees|kilometers|miles for AbstractSpatialFieldType

> Annoyingly, the units="degrees" attribute is required for fields extending
> AbstractSpatialFieldType (e.g. RPT, BBox). And it doesn't really have any
> effect. I propose the following:
> * Simply drop the attribute; ignore it if someone sets it to "degrees" (for
> back-compat).
> * When using score="distance", or score=area or area2D (as seen in BBoxField)
> then use kilometers if geo=true, otherwise degrees.
> * Add support for score=degrees|kilometers|miles|degrees
