Hi,thanks, that's valuable info, even if it doesn't help us until we are able to run 2.5. I noticed in the Fastmail branch on Github that the code currently only matches iOS 7. I assume you are running a version in production that also matches iOS 8.
if (is_ios && !strcmp(field.s, "os-version") && arg.s[0] == '7') {
imapd_id.quirks |= QUIRK_SEARCHFUZZY;
}
I have one question regarding the indexing in realtime. Does this *require*
replication? We currently have a monolithic Cyrus server, and consequently
don't have a sync log that squatter could use ...

According to Apple's manual, Mail searches all folders like this: "Searching looks at the address fields, the subject, and the message body."FYI when we found out about this change, we made all BODY searches from iOS become FUZZY BODY searches to make them work reasonably. http://blog.fastmail.fm/2013/09/17/ios-7-mail-app-uses-multi-folder-body- searches-by-default/ This works great with the xapian indexes we have, though it searches for "terms" not "sub-strings". On the other hand, there is one massive performance win. The xapian index is considered "complete", unlike the squatter index which just says "maybe". This means we can return a UID list directly from the xapian index without having to actually open any emails. With squatter, the index tells it which emails *might* contain the sub-string. It then has to actually open each email file to check if the sub-string is in there, quite a bit of slow & random IO. Also any emails not in the squatter index have to be opened and checked as well. As Bron mentioned in another post, our xapian index is kept up-to-date in realtime by indexing newly arrived emails into tmpfs, which are then compressed down to a disk at regular intervals. All up, the approach works amazingly well.
