search for: get_wild_query

Hi, I have some questions about searching with Ferret. I have a user index with first_name, last_name and full_name (which is just first plus last with a space). Here are a couple of questions: 1) If I store the fields tokenized, it appears as though queries are case-insensitive. However, for untokenized, the query is case-sensitive. How can I make the untokenized searches case-insensitive?
