+Currently when doing tab completion emacs queries the database and\r
+completes to any tag when adding but only completes to tags that are\r
+present in the message/thread/region when removing. However, since it\r
+queries the database it does this based on the current tags in the\r
+database not the current tags shown in the search view.\r
+\r
+This means that tag completion is not predictable and this seems\r
+undesirable. This series modifies it so that the tag caller can\r
+specify the possible completions (typically based on the tags that it\r
+believes are present). This means that the user know that -un<tab>\r
+will complete to -unread if he can see unread in the messages\r
+tags. (unread is a common stale tag as when you quit from a show\r
+buffer back to the search buffer the unread has often been removed).\r
+\r
+One side effect is that it solves the `large search' problem when\r
+doing tag completion on the very large queries that will be generated\r
+by the move to tagging by message-id rather than thread-id.\r
+id:1353763256-32336-1-git-send-email-markwalters1009@gmail.com\r
+(The tagging can use the batch tagging when that goes in).\r
+\r
+I think this makes the user interface more predictable/consistent but\r
+whether it is worth the change is less clear.\r
+\r
+Best wishes\r
