regex search and replace left and right boundary

For the given string, 

I can haz haz bacon. Mmmm. Tasty, tasty bacon.
       ↑                            ↑

I want to capture content bounded by the first string "az" and the last string "as".

In this example I cannot use ^$ anchors. I tried using:

\b(az).*(as)\b.

What am I missing?

This would find the longest possible match:

(?<=az).*(?=as)

For shortest match:

(?<=az).*?(?=as)
