[development] view filter on 3 or 4 zip code digits

I have a view that is pulling back a list of nodes. Right now, I can filter them based on a full 5 digit zip code. However, I don't have enough nodes right now to make that a good idea. There will be lots of zip codes that come back with empty results. My question is, can I make it only use the first 3 or 4 digits of the zip, and use a wild card for the 4th and/or 5th? Can I use a * in the search? Could I just swap out the last digit(s) of the user input with a *? -- Brett Evanson <mailto:brettev@gmail.com> brettev@gmail.com
