+Hello all,\r
+\r
+As part of trying to cope with an extremely high amount of email at\r
+work, after a couple years of using X1 Search on Windows in conjunction\r
+with MS Outlook and many years getting incredibly frustrated at the lack\r
+of, and then failures of, email search features built into linux desktop\r
+environments such as KDE and Gnome, I craved a better tool for linux.\r
+Recently, I stumbled on the combination of offlineimap and notmuch and\r
+I'm convinced that this will make my world a better place. I'm still\r
+finding my way in terms of optimum ways to tag and filter my email, but\r
+this is a fun ongoing task that will continue over the coming weeks and\r
+months and I'm seeing a light at the end of the tunnel. So firstly,\r
+thank you.\r
+\r
+So...One thing I'm struggling with is searching for emails in folders\r
+which contain spaces in their name. The IMAP server at work is Exchange\r
+based and I have Inbox, Deleted Items and Sent Items folders (among many\r
+others) all at the same top level. I'm using the default offlineimap\r
+configuration which uses '.' as the separator. After a sync I have...\r
+\r
+mail/maildir/\r
+├── INBOX\r
+├── Deleted Items\r
+...\r
+└── Sent Items\r
+\r
+....on the file system. These directories have the cur, new and tmp sub\r
+directories associated with maildir. All ok so far.\r
+\r
+I have several emails in Deleted Items and Sent Items. I can ls and cat\r
+them just fine. What I cannot do, however, is search them with notmuch.\r
+Reading the very helpful replies in this thread\r
+(http://notmuchmail.org/pipermail/notmuch/2014/019053.html), I thought\r
+I'd stumbled on a solution. However, searching with..\r
+\r
+notmuch search 'folder:"Deleted Items"'\r
+\r
+.. throws up zero results.\r
+\r
+Confusingly, if I sync a different IMAP account with offlineimap and\r
+index it with notmuch, I can successfully search folders which contain\r
+spaces in their name, but in that account, these folders exist *under*\r
+INBOX, eg\r
+\r
+mail/maildir2/\r
+├── INBOX\r
+├── INBOX.Deleted Items\r
+...\r
+└── INBOX.Sent Items\r
+\r
+So searching with..\r
+\r
+notmuch search 'folder:"INBOX.Deleted Items"'\r
+\r
+..works.\r
+\r
+So why the difference? AFAICT the syntax I'm using is correct and should\r
+allow the string to be searched in the Xapian database. I just don't\r
+understand why one directory level seems to make a difference between a\r
+successful and an unsuccessful search.\r
+\r
+Any thoughts?\r
+\r
+If it helps I'm running notmuch 0.19 and xapian 1.2.18 on Gentoo linux.\r
+\r
+I suppose I don't need to sync Deleted Items, and I can tag -inbox\r
+emails sent by me, but I'd still like to be able to search both these\r
+folders if I need to.\r
+\r
+Can anybody help suggest what could be going wrong?\r
+\r
+Many thanks from a very happy new notmuch user.\r
+--  Matt\r
