Ask HN: Is there anything similar to DocumentCloud for non-journalists?

I'm looking to be able to store pdf documents in the cloud and be able to search them. DocumentCloud looks perfect but I'm not in journalism. I'm having trouble finding an obvious alternative. Do you guys like any other services or know of a simple way to do this with NoSql? I was looking into using a hosted mongodb service but I can't find any information on searching binary data. Thanks for any pointers.
