Suppose I have this sentence:

"Peter Piper Picked a Peck of Picked Peppers"

and I wanted to extract out all the words that contained the letters "Pi"

is there a simple way to do it with regular expressions?

Try a pattern like this, assuming you are setting RegExp to not be case sensitive:

\b[a-z]*pi[a-z]*\b"
