AngularJS: How to clear query parameters in the URL?

I use

$location.search('key', null)

As this not only deletes my key but removes it from the visibility on the URL.

I ended up getting the answer from AngularJS forum. See this thread for details

The link is to a Google Groups thread, which is difficult to read and doesn't provide a clear answer. To remove URL parameters use

$location.url($location.path());
