This is what this regexp does
^ Start of the line, .{3,4} match any character but newline atleast
3 but not more than 4 times
not followed by 'd', not followed either 's' or 'k' or 'i' or 'p',
0 or more characters except newline, literal '.'
and finally fea. Is this what you want to match. Can you provide
some example strings.
