A few additional comments:
With the setting "search_fuzzy_always: 1" all searches use Xapian.
Otherwise searches from clients that don't use FUZZY run completely without
a search index. There is no fallback mechanism to squatter. You also need
to be careful with the conversationsdb. In my experience the DB is not
updated when syncing from a 2.4 server to a 3.0 server. That means that you
need ro rebuild each user's conversationdb manually using
