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 to index 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 found this here "Indexing PDF with page numbers with Solr" but it wasn't really helpfully.
I'm now splitting the PDF and sending each page separately to SOLR.
So every page is an own document with an id <id_of_document>_<page_number> and an additional field doc_id which contains only the <id_of_document> for grouping the results.
