Yes. Some metadata are extracted with Tika.
As you said, you should do that operation before indexation (means only index
what you really need).

Thanks for the reply. the attachment plugin I understand encodes content
before indexing it, this sounds like an expensive operation if we have lots
of pdfs. I was thinking extracting text from pdf early on instead and deal
with text instead.
Does the plugin also work for binaries like images?

You can use Tika by yourself (recommended). See how I did it in fsriver
project.
You can use mapper attachment plugin which is using Tika behind the scene
but gives you less control IMHO.
About versions, elasticsearch does not keep old versions around. If you need
that, you have to manage it yourself.

- Is there any literature on how to index pdf documents and binary formats
like images?
- Versioning question: If I update an already indexed document, I believe
ES will update the version number. I am wondering if it keeps the previous
document, what if I needed access to the previous document?
