Nicholas Knize commented on LUCENE-7179:
----------------------------------------
Oh, I do think the "quantization" issue (which I still think "encoding" is more
accurate) is separate from this issue. While I agree we "shouldn't care" that
its being encoded more than once, its already being encoded in the indexer. So
it seems more appropriate to just encode the raw test data for consistent
comparisons and not before adding the point to the document?
> GeoPoint and LatLonPoint test data should quantize once

> {{LatLonPoint}} and {{GeoPointField}} tests pre quantizes test data to ensure
> consistency with indexed (encoded) data. The pre quantized data then becomes
> indexed, undergoing another quantization. To guarantee numerical stability
> this should be changed such that the test data is quantized after indexing.
