Is there a way to see what words people are searching for on a particular topic?

[episodic]

For instance is there something that maybe google would offer somewhere I don't know about that would tell me which of the following is more popular searches?

Say:

photoshop vectors
photoshop cropping
photoshop glamour


These are just three randoms out of tons I'd like to test . . .

ANything like this?
