Thanks for the confirmation, took me a while to figure that out :-)

Yes, I'd have to find a way to pass some metadata into the tokenizer 
before feeding it each chunk. Kinda messy.

Yes, that's the conclusion I came to. It's easy enough to do, I'm using 
JavaMail to recursively traverse the mail file so I can separate out 
each mail and also deal with multipart mails as well as attachments, 
which I'm then feeding into Tika.

Thank you for the information :-)
