This is a temporary error that happens when the database is being re-indexed. Due to the huge number of posts, this sometimes takes longer then expected, and you may occasionally run into this error. You can try again in a few minutes and it should be back to normal.

The search database has been migrated over to a new server. Hopefully the crashing issue gets resolved with the new updates. There will still be a short reindexing window on early Saturday mornings which will result in the search function being briefly unavailable.
