Just to clarify, both `docValues` and `stored` needs to be set to false.
If one or the other are true then it fails.
At this point I question whether a field being a polyfield is causing this
issue. The testing I've done does not support that. Javadocs for
FieldType.isPolyField() state:
> A "polyField" is a FieldType that can produce more than one
IndexableField instance for a single value
The issue here is with stored fields because that's what is returned in a
search query. Indexed fields are not.
