How often is SEARCH ALL updated?

Does anyone know how often or when SEARCH ALL is updated?

The Reason I ask is that I changed the LANDING POINT for a parcel of my land (in ABOUT LAND). In SEARCH PLACES, the update to the LANDING POINT occurred almost immediately. IN SEARCH ALL, the LANDING POINT hasn't been updated and if I TP (from within SEARCH ALL) I still end up at the old LANDING POINT. It has been overnight since the update was made, but it doesn't show up yet in SEARCH ALL.

Thanks in advance for any guidance.

Every 12 hours. If you set the new landing point just before an update, it would change very quickly, but if you set it just after an update, you'd need to wait almost 12 hours. So it can be anything up to 12 hours.

I should have said that that applies to the Google appliance update - crawl and index. There's another update that also needs to happen - html page creation. I don't know how often that's done, or even if it's done all in one run, but LL have said that it could be up to 2 or 3 days before a change reaches the search results.
