Hello,
In the OP you say Yahoo and then Google?
Anyway, the point here is that you are querying for your exact domain name, which has 3 words in it. And usually in this case, it should be high in rankings, unless it is ultra competitive. I believe keyword in domain is one of the highest if not the highest factor for Google, not sure Yahoo.
So it seems to me your test shows that this keyword is not too competitive.
