What is extractable from an image using the attachment plugin?

Hi,

I am trying to work out the limits of what is possible with the attachment
plugin for elasticsearch. Working with document based attachments is
absolutely fine and I have no problem with that. However, I would like to
know what exactly can I extract from image attachments? Other than image
metadata (e.g. EXIF) can I expect the plugin to perform a sort of OCR
function, and recognise when an image contains text and then make that text
searchable?

I've tried it locally, and it didn't work, but I wanted to ask other users
in case they've successfully been able to get this to work, and I'm doing
something wrong.

Thanks!

Hey,

the attachment plugin does not use any OCR recognition. It uses Apache Tika
for content extraction. See http://tika.apache.org/
