Can my public files be searched on the internet?

Yes, your public files can be searched on the internet. 

In the future, you will be able to move private files to public, but once they are public you will not have the ability to make them private again. 

This is a new powerful type of innovation and technology that offers many exciting possibilities. However, we urge you to carefully consider what you want to make public, because once it is uploaded to the permaweb it will be there forever.
