Tomorrow’s release requires us to update the main server and the search servers at the same time. This presents a bit of a chicken-and-the-egg problem: We need to build new indexes even before we’ve migrated the database to our new schema.
To accomplish this, I’ve stopped index updating and created a separate database that will allow me to build some indexes that will be a few hours out of date when we release tomorrow. They will be slightly old, but at least we will have indexes that work.
I expect the indexes to be up to date about 3 hours of the release is complete. If you find the indexed search out of date, please use the direct search in the meantime.
Sorry for any inconveniences this may cause.
