I want to build a regular expression that will find certain characters in a\nfield. For example:\n\ni,n,t,u,o,n\n\nall need to be present (at least once) for the RegEx interpreter to label\nthis search True. The order is not important, and case should be ignored.\n\nI tried\n\n[Ii][Nn][Tt][Uu][Oo][Nn]\n\nand\n\n[Ii].*[Nn].*[Tt].*[Uu].*[Oo].*[Nn]\n\nNo joy.\n\nAlso tried use of ^ and $ but I'm not sure how to implement them, and whether\nor not they are required.\n\nSo basically I'm stumbling around in the dark. But I want to learn. I've\nviewed several tutorials on-line, but this subject is so obtuse to me that\nit's difficult even getting started.\n\nAny suggestions would be greatly appreciated.\n\nThanks!
