I've got SOLR happily running indexing a list of department names that contain US states. It is working well however, searching for "Virginia" will turn up results containing "West Virginia", and while certainly helpful for some business requirements, is not in ours.

Is there a special way of saying that a query for X must not contain Y (I don't mind crafting a special query for the case of "Virginia"), or can I only do this post-query by iterating over the results and excluding results with "West Virginia"?
