Recover missing bit of Open Office document?

Somehow I’ve lost part of a document I’m writing in Open Office. Either I deleted it, or it somehow went missing during OO’s autorecovery procedure. I’m not saving versions, and my backup files are all the most recent version, which is the one with the bit missing.

Is there any other way to get back the missing text? I doubt it, and if not, I’ll just rewrite it (it wasn’t huge anyway). But I’d rather not if I don’t have to.

Thanks in advance for any ideas.
