I know that it is possible to search for information on a particular site by using the site key via Google and etc.
For example:
Name Lastname site:facebook.com
But how does a query look like, if I want to search info within 2 or more websites ?
Unfortunately this method wasn't return any results:
Name Lastname site:snapchat.com site:facebook.com
A pipe operator is what you're looking for ;D
[search term] site:snapchat.com | site:facebook.com
You could also do the following and get similar results
[search term] site:snapchat.com OR site:facebook.com
