I am migrating a site from SP2010 to SP2013. One of page contain a search result webpart. By define the querystring like this:
It will return only the defined scope results.
However, since SP2013 no longer provide Scope, can I perform similiar trick with querystring? I have setup a Result Source "Hotnews" on my SP2013 farm. But I don't know how to make it work in querystring way.
