How does the information change in each of these customer's documents? I would think if they were very dynamic then updates to the single index would not be great for you. But if the updates were just now and then, then given the performance of lucene that the single index would be just fine. i was using a single index for most of my applications that use search till I ran into a commenting system for a blog like application. I realized that I didn't want to be updating the main records index for each comment, so I split that off. I've been pretty happy with that choice so far. So, anyway, it seems like one index would be easier and given that document count you are talking about, I am sure lucene will handle either fine as far as speed and mem.

I have 100,000 customers and I want to provide them with personal searching for their documents and sometimes to include company documents in that search. 1. 100,000 customers with 10-20 small document each. 2. Company 5,000 documents, specification, papers, research, etc. 3. Customers can search their own documents and company document. P1: Do I provide an index for each customer and allow them multiple index searching, into company document when they need it? OR P2: Do I provide one large index for all my 100,000 customers, adding a field for customer ID so searching can be constrained, so they won't/can't search across other customer's documents, and then categorize company documents so customers can do multiple index searches into company documents? After writing this out I realize that P2 is probably the wiser choice, less complicated, but I would like to hear from other Luceners. Lucene in Action is one of the best written books in my library of ~300 CS books. It ranks in completeness and clarity up there with works by David Geary, Martin Fowler, and other Hatcher greats like Java Development with Ant. Thanks Otis and Erik.
