Well - its not that I want to ignore the non-numeric groups, we're giving
the user the option to either search for an exact part number, a substring
or by part family (yes, it is an electronic parts database).
Creating a second field would be a serious pain as far as maintanence goes.
In many languages I could store the search string as an array and loop
through the array inserting '%' symbols in between each character. I'm not
aware of any CF way to do this.
