Michael McCandless commented on LUCENE-5989:
--------------------------------------------
bq. If we fix this .document api to allow a StringField to have a binary value,
maybe it could help with merge code.
This would be very nice ... I struggled some with it, but got stuck with
StorableField.stringValue() returning String. I think we need to keep that
because that's also the API apps use to retrieve their stored fields.
But the default merging operates on StorableDocument/StorableField, so I'm not
sure how to separate the two. Really there are two concepts: the "schema" for
this doc (did it store a binary or string value for this field), and what's
used to represent a string value (byte[] vs String), and both concepts are
being smooshed together into this API.
Maybe we could baby step here, and just change StoredFieldVisitor.stringField
to take byte[]? I know this doesn't help all the stupid work we do during
default merge to decode/encode but at least it's a start ...

> 5 years ago (LUCENE-1458) we "enabled" fully binary terms in the
> lowest levels of Lucene (the codec APIs) yet today, actually adding an
> arbitrary byte[] binary term during indexing is far from simple: you
> must make a custom Field with a custom TokenStream and a custom
> TermToBytesRefAttribute, as far as I know.
> This is supremely expert, I wonder if anyone out there has succeeded
> in doing so?
> I think we should make indexing a single byte[] as simple as indexing
> a single String.
> This is a pre-cursor for issues like LUCENE-5596 (encoding IPv6
> address as byte[16]) and LUCENE-5879 (encoding native numeric values
> in their simple binary form).
