Using the find command in Krunner

I am a big fan of krunner. But eversince I came across it I have been disappointed by its search function. When I am searching for a specific expression I normally use:

find . -iname '*heavymetal*'

The find-command ist very useful on my view. I frequently try to search with krunner but it is not presenting sufficient output.

So my question is:

Either: Is there a special syntax within krunner, which is giving me the same output or a compairable output to the find command?

Or: Is it possible to implement the find command into krunner or make a small script which can be implemented into krunner?
