Hi PK,
For this issue, I have a test on my local server, when the result is not in an item just a meaningless result on site default page, the url is displayed as
http://servername/sitename. In addition, when you access site default page, you needn’t type the specific url. Based on my understanding, it’s by design, you cannot change it, because the other results url are specific.
