Issue Description - In the current environments, when you've performed a search on knowledge search, scrolled down the list of articles, and you decided to perform a second search, when you search a second time, the results will not default to the top (ie to the most relevant articles), instead, the view stays where the previous search ended.

Idea Description - For the second search to refresh the view back to the top on the list of articles, not remain half way down the list.
