If you really need an index on zip + street + lastname + firstname you can always include the cdx into the encrypted files (as you probably know)Sure. I'm thinking more of something like the US Social Security Number (SSN): index on that and it'll be visible in the cdx. Just something for people to think about.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
