Devon: To find names starting with 'foo' just use 'foo'&names . To find names containing the substring 'foo' use '*foo'&names . To find names NOT containing the substring 'foo' , use '~foo'&names . (You can put the sigils '*' and '~' anywhere in the pattern. I prefer them in the front.)
-Dan PS: A niggle: 'foo*' is not a regex; "wildcard search" would probably be a more appropriate term. In my utility drawer, I have a fancier version of names which supports true regexen.
