Comment 2 for bug 885542

This sounds like a good idea to optimize search times, but this is more of a feature request and I suspect we should avoid an Ubuntu delta for it. Would you mind opening a bug/feature request against Thunderbird on Bugzilla for this? That way the Thunderbird developers can determine if this can be incorporated into their search algorithm, and if it would benefit the majority of users, as it's possible the current behavior is based on usage data showing that, on average, users search for old mail more often than recent mail.
