To combine multiple fields into one index - or to have one field per index? I ask because MySQL will appear to select the best possible index for the query and sometimes it's wrong - I read somewhere you can control which index it uses, but if you had a "combined" index would this make things any more/less effective?

Figured someone might suggest that - I will have to look into it.
