It's almost never a win to index a text field, unless This is not a key on a text field. The keys are: mail_list (example, the PHP mailing list=1) mail_year (1999) mail_month (July=7) Yes it is a multi-key index, and the matches are exact. Someone else asked why I have separated these fields out from the mail_date. If I didn't, and I wanted to see the messages for this month, I'd have to regex and that would overwhelm the database.
