You might want to try naming submissions like this as: "Ask HN: Review my improved Mail.app search algorithm", or "Tell HN: I made Mail.app better!" On the other hand, I'm new here, so what do I know? :-)<p>Great looking site btw, although I've never had a problem with searching for mail with spotlight / Mail.app and nothing I see here convinces me of the benefits. Maybe more obvious and cool screenshots?
