Alan Woodward updated LUCENE-7679:
----------------------------------
Attachment: LUCENE-7679.patch
Here is a patch that re-organises how MemoryIndex builds its internal field
Info structures. If an IndexableField is passed to addField(), we re-use as
many of its FieldType settings as possible.
I needed to make FieldInfo.setDocValuesType() public, but that brings it into
line with .setPointDimensions() so I don't think it's too bad a change?
> MemoryIndex.addField() ignores some FieldType settings

> MemoryIndex never omits norms, which means that it can produce incorrect
> scores.
