You can encode (e.g. base64) the binary data to get a String
and store the String.

I was hoping to avoid the overhead of encoding/decoding, but it looks like
I'll have to do that :(

While on the topic, I noticed in the Field class that we have a "isBinary"
boolean flag, however this always gets set to false in the constructors as
well as the default value, and I can't even see a usage of this flag at
write-time. What's the point of this flag, a feature for binary fields that
was never implemented? I'm talking about the latest sources now, by the way,
1.9.something.

Binary fields can be stored, but not indexed.

Please see the following version of the constructor:

public Field(String name, byte[] value, Store store) ;

isBinary flag is set to true.

Thank you,

Which library can Base64 be found in?
