Alan Woodward updated LUCENE-7684:
----------------------------------
Attachment: LUCENE-7684.patch
Here is a patch implementing this. Payloads are detected by checking for a
PayloadAttribute when adding a TokenStream to the MemoryIndex. If terms have
already been added with no payload, then an exception is thrown - I think this
is a reasonable restriction, as you should generally use the same Analyzer for
all values in a multivalued field.
I also needed to make FieldInfo.setStorePayloads() public.
> MemoryIndex should store payloads per-field

> Currently MemoryIndex will store payloads for all fields, or for none. It
> would be useful instead for it to store them per-field.
