find a pattern is string with wildcard

[MART1]

Hello

I have a list of addresses and I need to find those records that contains R*S  (* meaning any possible character).

R*S could be anywhere in the string.

I've tried combining different fucntions (SCAN, INDEX, CONTAINS, wildcard..) but I cannot get it to work.

Any idea would be very much appreciated!

thanks
