How to extract a string that starts with certain words or letters?

I'd like to use rex to extract the event string that starts with certain words or letters, possibly ends with certain words or letters. For example I have a event string like "blah blah blah Start blah blah blah End". I can do something like: mySearch|rex field=_raw "Start(?<"myField">.*)End" I want my result not only "myField" but also including "Start" and "End". How can I do it?
