I thought new posts showed up after 5 minutes? I posted a reply to this thread http://forums.digitalpoint.com/showthread.php?t=1747308#post13918116 last night and when I click "View Forum Posts" or "Find all posts" from my profile that post isn't showing up.
Yeah, there's something weird going on where the occasional post doesn't get inserted into the delta index immediately like it's supposed to. It's not something I've been able to actually replicate, but I've seen it happen (like yours). I need to start doing some back end logging of everything so I can trace it around. In the meantime, the posts that aren't getting indexed will show up in search whenever the full rebuild is done (currently that happens once a week).
