I found an easy way to search notes made in the journal. If you send the notes to evernote as an image (I tried png format) they become searchable. In theory you can send a pdf as well (at least from windows) but I think you need to pay for the premium account in order to make it searchable.

Wouldn't it be cool if we could sync the notes directly from the journal with evernote? Maybe a partnership between EE and evernote?
