Yes (and the whole left side constitutes *the* search pattern). > However in a plain regexp look ups, only those inside the parenthesis are > being matched... [snipped] No, only those inside the parenthesis are being *catched* into the $1..$n variables. For the catching taking place, the *whole* regex must match, and what's catched is/are part(s) of what matched.
