I definitely second the idea that you don't want to expose your Solr instance directly to the world -- it only takes one bored vandal to wipe your Solr index. We have a Java servlet sitting between our AJAX calls and Solr. In the typical case, it just builds the Solr base URL (picking the right core, ensuring that all requests go to a /select handler) and passes the rest of the URL parameters straight to Solr.
Of course, once you have the middleware in place, it's easy to add in extra stuff like transforming the results into other formats, doing more fine-grained access control (we check IP addresses and automatically add filter queries to restrict search results to the items available to the user's IP), etc.
