Ali, Sounds like a good choice. It's pretty standard to store the primary storage id as a field in Solr so that you can search the full text in Solr and then retrieve the full document elsewhere.
I would recommend creating a document structure in Solr with whatever fields you want indexed (most likely as text_en, etc.), and then store a "string" field named "content_id", which would be the Accumulo row id that you look up with a scan. One caveat -- Accumulo will be protected at the cell level, but if you need your Solr search results to be protected by complex authorization strings similar to Accumulo, you will need to write your own QParserPlugin and use post filtering: http://java.dzone.com/articles/custom-security-filtering-solr The code you see in that article is written for an earlier version of Solr, but it's not too difficult to adjust it for the latest (we've done so in our project). Once you've implemented this, you would store an "authorizations" string field in each Solr document, and pass in the authorizations that the user has access to in the fq parameter of every query. It's also not too bad to write something that parses the Accumulo authorizations string (like A&B&(C|D|E|F)) and interpret it accordingly in the QParserPlugin. This will give you true row level security in Solr and Accumulo, and it performs quite well in Solr. Let me know if you have any other questions.

I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want. I can do all this through him who gives me strength. *-Philippians 4:12-13*
