How do I find cases that involve an illegal search & seizure while the person was in a parked car? ?

I need to find cases that involve a person being in a parked car and being unreasonably searched ("pat down" and car search). The officer conducting the search found an ounce of marijuana and arrested the person. The defendant is claiming that he was racially targeted and that his 4th Amendment right was violated. Does anyone have any case names that are similar/ I tried searching FindLaw.com, but came up with nothing. Thank you for any help you can give me.
