Shai Erera commented on LUCENE-5989:
------------------------------------
bq. we could maybe instead just add a ctor for StringField taking BytesRef...
We could also rename StringField to KeywordField, making it more obvious that
this field isn't tokenized. Then a KeywordsField can take a String or BytesRef
in ctors.
> Add BinaryField, to index a single binary token

> 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).
