Bypassing security trimming in SharePoint

I had a requirement to allow users to search for documents that they don't have access and found this artice:-

However, when do some testing to validate the above, I found that it is not working. Reason being, MS Search has security trimming during query  itself.

I still haven't found any workaround for this.
