EMD is Exact Match Domain.
It's where the words in your domain, exactly match the words you've used in your search, so, PinchBolts.com would be an exact match domain for the Google search - pinch bolts.
If a Google search for the words in your domain, exceeds the 10,000 requested results, then your domain name could be what the poster is looking for.
