I am using the search plugin of welcome.totheinter.net for multisite search (originally relating to wpmu).
Recently I found if I do a search of certain term like 'success', then it shows up posts that do not exist!
And not just that, if I am logged in as admin, it would even show edit button and take me to backend page - of course the page does not have any update or other options
The frontend URL does give 'not found' error
I am posting this, because, i somehow feel that this has to do with the core, and not the plugin.
