factory and controller

Could you also please explain the meaning of:
function($q, elasticsearch, $location)

you pass to the factory?

and:
function(recipes, $scope, $location)
you pass to the controller?

I got the sense you pass a value from the controller to the factory, is it that?
(from input search field, to factory, which produces the obj of results)
But I didn't understand how is done exactly.

Also,
what's the need of:
['$locationProvider', function($locationProvider){
$locationProvider.html5Mode(true);
}]

in the module?
I read your blog but didn't understand these passages.

Thank you!
