Get page number of searchresult of a pdf in solr

[dev]

Hello,

I'm building a web application where users can search for pdf  
documents and view them with pdf.js. I would like to display the  
search results with a short snippet of the paragraph where the search  
term where found and a link to open the document at the right page.

So what I need is the page number and a short text snippet of every  
search result.

I'm using SOLR 4.1 for indexing pdf documents. The indexing itself  
works fine but I don't know how to get the page number and paragraph  
of a search result. I only get the document where the search term was  
found in.
