Is it possible to do partial index on Apache Solr 4?

Question

We have around 5 projects which use one API for Products(Categories, Brands are also stored there).

But each project has it's own range of products, for example project1 can have ipod 4, iphone 5 as products list, project2 {ipod 4, iphone 4, macbook, das keyboard}.

Now idea is whenever someone searches for "ip" in project1 web-site it should return {'ipod 4', 'iphone 5'}, if search query is 'macbook' empty set will be returned.

But in case if someone will be searching for "macbook" in project2 website it will return {'macbook'}

So question is, how to do that using Apache Solr 4? Any ideas would be much more appreciated

Thanks beforehand
