For example you're searching a first+last name.
Then add "John" to only search theses terms. Sure you can do "John" "Smith" for example
Now you can add an other term to only search on a specific site (personnaly i directly search on-site):
"john" "smith" site:domain.tld
You can do that with all infos you get like a brute you'll may find the dude you searched.
