What do you mean by "word location"? The number on the page? What purpose
would this serve?

I think that you might be confusing things:
* If you have the full-text, you can highlight where the word was found. Solr
highlighting handles this for you, and there is no need to store word location
* You can have different images (presumably, individual scanned pages) linked
to different sections of text, and show the entire image.
Highlighting in the image
is not possible, unless by "word location" you mean the (x, y) coordinates of
the word on the page. Even then:
- It will be prohibitively expensive to store the location of every
word in every
image for a large number of documents
- Some image processing will be required to handle the highlighting after the
scanned image is retrieved
