If you want to use regular expressions to do it, easiest way would be to use the character class for whitespace before and after your preposition. However don't underestimate the power of the CF list processing functions, think of your search term as a list seperated by whitespace and you can use any of the CF list functions. ______________________________________________________________________ Why Share?
