about the radar : LOTROExtreme

I was just wondering i see there is a search feature for the radar. I am assuming it is suppose to search for Mobs in a certain distance perameter and I couldn't get it to work. My question is does it work or is this just sorta like a sample script?

It searches the object names shown on the display. If a match is found it will play a sound and show the name in red.

thx
