So what I'm taking away from this is that I can index a text column, but that is relatively new. Based on experience with technology I'm going to guess it's not a very efficient index or search function yet. CHAR seems to be well entrenched, and the favorite for any column I may need to search against. I just need to be warry of the size limits and account for them in my program and data entry. Does that seem to be the consensus?
