382 This buffer contains the results of a \"notmuch search\" of your

385 number of matched messages and total messages in the thread,

389 Pressing \\[notmuch-search-show-thread] on any line displays that

392 tags from a thread. The '\\[notmuch-search-archive-thread]' key
393 is a convenience for archiving a thread (applying changes in
394 `notmuch-archive-tags'). The '\\[notmuch-search-tag-all]' key can
395 be used to add and/or remove tags from all messages (as opposed

397 this will also tag matching messages that arrived *after*
398 constructing the buffer.

401 filtering the current search based on an additional query string,
402 '\\[notmuch-search-filter-by-tag]' for filtering to include only
