You can do a `var search = this.window.location.search;` before this line and use it in all of the calls to `Url.searchParam`. If you look in #890, I have added a helper fucntion to imports like this: `this.importSearchParam` - see https://github.com/mozilla/fxa-content-server/pull/889/files#diff-af500bac5338814fda67ec4de209ac46R371.
