I perform a search and get my result.
I click on a search refiner (by author) and get my subset of results.
I again click on this same author in the refienment panel and the author refinement is removed and I am back to my full results.
Is this expected behaviour?
URLs will help explain
I search for the book
http://xxx/search/pages/results.aspx?k=the%20book&s=All%20Sites
I click setup under author
http://xxx/search/pages/results.aspx?k=the%20book&s=All%20Sites&r=author%3D%22Setup%22
I click setup under author a second time
