Re: How does the pattern work in the Search function?

Thanks, Dennis, but I already saw that in the documentation and it doesn’t answer my question. I need to know how to use the Pattern parameter of the Search function. Here’s my behavior that’s using the Search function to check for a PO Box: http://imgur.com/xyTq9.png.

If I type “PO Box” into Text Input 4 and click the button that runs this behavior, I get no message. If I type “asdf” and click the button, I get the message. So I’m not understanding how the Pattern parameter of the Search function is supposed to be used to match what I’m looking for.
