Conversations.db is an index over lots of interesting bits of the message, but the key part that's used by Xapian is the mapping from G key (aka: GUID, aka: sha1 of the message RFC822 data) to individual email. It's used for deduplication and for mapping from results to messages.
The data in conversations.db is added and removed in real time as messages are appended and updated in the cyrus.index. The data in the xapian databases on the other hand is append only - so you can wind up with hits that no longer map to existing emails. The way to solve that is with a xapian repack that filters messages - which can be done using the -F flag to squatter. Cheers, Bron.
