Navigate to AngularJS's SPA with QueryString parameters

The link to my SPA is constructed of an absolute URL + Query-String parameter as the following:

http://127.0.0.1/Pepole/Index?personId=[some_ID]

And my route configuration is:

tmc.config(['$routeProvider', function ($routeProvider) {
        $routeProvider.when('/', { templateUrl: '/People/Person', controller: peopleController });
        $routeProvider.otherwise({ redirectTo: '/' });
}]);

Given my config, when routing to /, how can I retain the personId parameter so it would be available in the respective controller (peopleController) and I will be able to access it.

http://docs.angularjs.org/api/ng.$location#search

search(search, paramValue)

This method is getter / setter.

Return search part (as object) of current url when called without any parameter.

Change search part when called with parameter and return $location.

Parameters
search(optional) – {string|object<string,string>=} – New search params - string or hash object
paramValue(optional) – {string=} – If search is a string, then paramValue will override only a single search parameter. If the value is null, the parameter will be deleted.
Returns
{string} – search

function SomeCtrl($scope, $location) {
    $scope.personId = $location.search().personId;
}

Inject $routeParams in your controller and then simply call $routeParams.yourQueryParameter.

For example:

function SomeCtrl($scope, $routeParams) {
    $scope.personId = $routeParams.personId;
}
