Mac Mail Search Operators - Any

What is the search operator for searching for emails using "Any"?

My understanding is that I can search for emails sent TO someone by using the "To" operator (e.g., "To: john@gmail.com") and FROM someone using the "From" operator (e.g., "From: john@gmail.com").

What if I want to search for any email (To or From)? In other words, what is the search operator for searching for emails using "Any"?

"Any: john@gmail.com" does not work.

Thanks!
