We use the SharePoint search to display news from various team sites. Sadly this leads to all items which are displayed being marked as 'accessed' by the various users.
This is very confusing to our users as they have not actually accessed the content, but only the preview. Especially as this information is surfaced on the SharePoint Home page (_layouts/15/sharepoint.aspx).

The Microsoft support claims this is as designed. Though this concept is different from most of the search behaviour out there. Please change this.
