Search for Message ID

[Harley77]

I've done it before, but for the life of me it's isn't mentioned anywhere that I can find again. I want to search a mailbox for a particular email by its Zimbra ID (ex 97401, 78994, etc). I was even able to search for multiple id's. Just typing the number gives you nothing, there was some kind of search filter prefix I had to use.
