Different Solr Instance with different indexed data?

I'm working on e-Commerce site which is based on ASP.NET MVC3. I've implemented SolrNet 3.6 for improving search.

For that, Only one solr instance is running which is served by Tomcate Apache 7.0 .

My client is demanding to develop another e-Commerce site using SolrNet which should be by served same Tomcat server.

So is it possible to invoke multiple solr instance having different data? If yes then How can I achieve this?

Solution

To do this, you will need to change your setup to have multiple cores. Your Solr install should have an example configuration for this kind of setup under example/multicore. In case you can't find it, have a look in Solr svn repository.
