Past 24-hour search is broken?

Uh-oh, this doesn’t look good:
Someone reported exactly the problem we are having, but no solution has been suggested
phpbb.com/phpBB/viewtopic.php?p=530636#530636

And this one makes me think we should disable the search link once and for all
phpbb.com/phpBB/viewtopic.php?p=699624#699624

And this one proposes a solution of some kind (but I don’t quite understand it)
phpbb.com/phpBB/viewtopic.php?p=451275#451275

So it looks like we’ll be without the 24 thing for now. I’m hoping that the next version of phpBB, which I am expecting in a few months, will accomodate this problem.
