I want to build a regular expression that will find certain characters in a field. For example: i,n,t,u,o,n all need to be present (at least once) for the RegEx interpreter to label this search True. The order is not important, and case should be ignored. I tried [Ii][Nn][Tt][Uu][Oo][Nn] and [Ii].*[Nn].*[Tt].*[Uu].*[Oo].*[Nn] No joy. Also tried use of ^ and $ but I'm not sure how to implement them, and whether or not they are required. So basically I'm stumbling around in the dark. But I want to learn. I've viewed several tutorials on-line, but this subject is so obtuse to me that it's difficult even getting started. Any suggestions would be greatly appreciated. Thanks!
