How do you search for more than 1 keyword?

How do I use the rforum search capability to look for posts that contain
2 words or phrases?

for example, there;s apost that I know for sure contains the words
“customers” and “accounts” – how would I find that post?

I tried entering “customers accounts” and “customers and accounts” but
no dice.

Couldn’t find any little “how to search” page, either.
