No,
Just the stuff in the database, and just the stuff in the forums.
The books themselves are just files on the server. The text content of the site is in the DB, the forums are in the db and the logs of the site and the logs of the forum are in the db.
The only tables with full-text indexes are the Message, Topics, Forum tables.
I have upped the memory, cpu, and doubled the IOPS on each of the virtual disks (they are on a RAIN).
Going to keep monitoring, there is a forum upgrade available, but don’t want to do that while beta is going on.
The biggest problem with migrating to a new forum platform (or web platform) is content migration, getting the history of the forums over.
I supposed I could have a “historical forum” and a newer one, but that’s not ideal for search.
Anyway, I”m next going to hack the forum log tables which are huge and basically contain craploads of debug information.
