isolating inbox email searches in outlook

One of the features in Entourage which i can't find in Outlook is being able to isolate your search within your email inbox/sent/deleted folders.  In Entourage i could type in someones name and the emails from that person would be the only emails that the inbox would show me.  Right now, i'll use the 'arrange by' tab and then 'from' and the emails will all be arranged by people's name but they WILL NOT be ISOLATED to the specific name i want.  any answers? it's driving me nuts.
