Can anyone help me to write a regular expression that matches "ecard", but not "scorecard" (without the double quotes)

Many thanks

Try "^ecard". ^ indicates the match must start with e.

"[\ ]ecard[\ ]"

gives exactly "ecard"

I'm trying to make it work for following conditions (which currently dont work):
ecard at the begining or end of the line.
