search alternatives

I have a question about possible other search options, or plugins in wp. I have an intranet site that we use to give users access to various documents and sales reports. There are literally hundreds of them. We use the Content Control plugin to restrict access to documents mainly by departments. You don’t want sales people seeing commission reports. And we use Memphis Document Library to upload and store the files.

Content Control works great restricting access to contents on a page, including links and libraries. The problem is if someone uses search to hunt for a document, security goes out the window. The search will find matches across the entire site, and the user can access any of them since they are direct links and not accessed from their page.

Does anyone know of a search plugin that would return the page the document is located on as apposed to a link to the document itself? Or any other ideas or suggestions?

Thanks.
