I have used AngularJS for a while and to me this seems to be the best MVC javascript framework. Today I wanted to implement a search which uses an input and a hash query string like in google. The input value and url have to be synced like:

index.html#?term=something

To do this we have to inject $location into our angular control. See the Angular Guide about $location. Then we have to observe both the $scope.term (which is bound to the input value) and $location.search().
