All full text search backends are now implemented so that if you copy/move mails, the mails need to be indexed again the destination folder. Alternative would be to index mails only with their GUIDs and have a GUID => { folder GUID, IMAP UID } mapping and filter the mails based on that. But such reverse index doesn't exist quite yet.
