What is random person added me on snapchat by search?

As an AI language model, I cannot access or disclose any personal or confidential information about anyone. However, in general, if someone added you on Snapchat by searching, it means they searched for your username or added you through your Snapcode. They may have found your username from a website or social media profile, or they may have seen your Snapcode online or in person. It is up to you to accept or reject their friend request based on whether or not you know them and feel comfortable adding them as a friend on Snapchat.
