Simpy.com has a similar setup. You have to be careful about open files, making sure you don't run out of open file descriptors. You'll also want to minimize IndexReader/Searcher/Writer open/close as much as you can. The good side of this setup is that searches go against small indices, you don't need to always add "AND user:XXX", and if anything goes wrong with one user's index, it's easy and fast to rebuild.

Hi, Iam currently working on indexing the documents present in a web based document management system. The system currently has around 200,000 users and each user has approximately 10 to 100 documents.We currently have around 50 GB of data. The system should allow the users only to search across his/her documents. Currently our system is designed such that each user has a separate index. The index size for each user is around 500KB to 5MB approx. For each document added by the user a indexwriter is created and for each search by the user a indexreader is created. ( I think it may not be a good idea). Can some throw some light on what kind of issues we might face with this kind of setup? Or should we have a single index. add unique user id as a field in each document. Search with user id added as a filter.
