In my never ending quest to find a suitable solution to my search requirements in Ghost, I finally came across Ghost Hunter

The "installation" and integration of it doesn't look overly friendly from an initial glance but it might be something I spend some time doing. I'm not sure yet.

The lack of an easy plugin system is certainly a negative for Ghost on occasion.
