factory and controller about angular-elasticsearch-demo

[adambard]

The factory is just a function that constructs a service object, which sounds fancier than it is; in this case, the returned service is called "recipeService" and the returned service looks like:

        return {
            "search": search
        };

where search is the function defined immediately above this line that actually does the searching.

Then, the controller has access to recipeService, which it uses to actually perform the search. All this could be defined within the controller perfectly well, it's just a matter of separating the api from the implementation.

HTML5 mode just lets you use URLs that look like example.com/my/path instead of example.com/#/my/path, and I think it also gives better access to query parameters, I can't really remember.
