title: SharePoint 2013 search shows strange result count
body: <p>OK, I just converted my 2010 solution to 2013. I use the search web parts for an article archive. I have configured it to only show content type of type "Artikkel" and to show 10 entries per page. When I load the page, it shows me the first 10 articles, but in the footer it says "About 109 results" and it only has page 1 and 2. When I navigate to page 2 it changes to "About 73 results" and page 3 appears. When I click page 3, it says "About 67 results" and page 4 appears.. and so on.... See images. This is in IE, in FireFox it is the same behavior but the numbers are different. Whats going on here?</p>
