Question: Seeing how much a keyword is searched over time

Hi, I know I ask a lot of questions, but i figure thats how you learn. I have micro niche finder and seem to have found a great niche. However before I go through and purchase the domain I want to see how the exact keyword phrase has done over time.

Micro Niche Finder has 1000 searches this month but I want to figure out the searches over the course of the year to make sure that its not just a random occurrence or a seasonal one.
