• Set source(s) on creation

     var s = new Search({
        sources: []
        });
        s.startup();
  

• Add to sources

     var s = new Search();
     var sources = s.get("sources");
     sources.push({//new source});
     s.set("sources", sources);
     s.startup();
  

• Set sources

     var s = new Search();
     var sources = [my sources];
     s.set("sources", sources);
     s.startup();
  

  search.watch("activeSourceIndex", function(){
  var activeSource = search.activeSource//.name;
  console.log("Current Source", activeSource);
});
