Hi, I have a similar problem.
I have an intranet searcher, I have VIP user and normal user. Vip user could search both normal documentation as Vip documentation. The way of solve it with nutch are use the subcollection api. I use in the past lucene api, I create two index and I make two search for the VIP user. I make a "manual" merge between the two search result. I think use nutch because I need search more file types and I need add a internet web pages to the normal user index. Thanks You
