Sebastian, sounds like an exciting project.

Hm, since this approach is very special, I would suggest to do something easier. You already got tools to retrive the word and the word's position from the image, right? What would be, if you add a field to the schema.xml with a preprocessed input-string. I.e: You got two fields: "page's text" and "page's text's word-positions". Page's text's word-positions needs preprocessing outside of Solr where you add the coordinates of the words . This preprocessing will be a little bit tricky. If the 10th word is "Solr" and the 30th word also, you do not want to have "solr" two times with different coordinates. In fact, you want to store both coordinates for the term "solr". However, on the Solr-side you can add this preprocessed string to a field with TermVectors. If your query hits the page, you will get all the coordinates you want to get. Unfortunately, highlighting must be done on the client side.
