Interested in getting started with Solr+Flask? This is a boilerplate that I built that might get you off the ground. It's a fabric script that helps you to setup Java, Jetty and Solr on Ubuntu (tested on 12.04). It also creates and initializes a Solr core based on provided schema files.
You can find it Jetty+Solr Fabric Boilerplate
