I can’t work out why Apple’s applications don’t utilise Spotlights ability when it comes to searching for items within them. Take this as an example. If I search for Saft inside Mail, so that I can find my registration details, it returns nothing.

If I then do exactly the same search via Spotlight, it shows four results under the email messages.

I’m just wondering why one of Apples own applications would have such a discrepancy when it comes to searching?
