Searching for someone's name can at best give you suspicions, but name collisions are so common that you can't know whether the person you found mentioned online is the same you wanted to find out about.
Personally, I have almost no real-name presence on the internet, so the top result for my name is some other guy's Instagram account. You might spend a lot of time looking at his posts, but that won't help you learn anything about me.
