Within a SharePoint document library, it is possible to add a link to another URL, (document or web page). When this item is returned in a search result the link SHOULD open the document or page the link points to, instead it opens a blank page, (the "contents" of the link). I am not sure if this is by design or a bug, but the action should be chnaged. As an alternative, such links should not be included in search results.
