NOTMUCH-SEARCH(1)					      General Commands Manual						 NOTMUCH-SEARCH(1)

NAME
notmuch-search - Search for messages matching the given search terms. SYNOPSIS
notmuch search [options...] <search-term>... DESCRIPTION
Search for messages matching the given search terms, and display as results the threads containing the matched messages. The output consists of one line per thread, giving a thread ID, the date of the newest (or oldest, depending on the sort option) matched message in the thread, the number of matched messages and total messages in the thread, the names of all participants in the thread, and the subject of the newest (or oldest) message. See notmuch-search-terms(7) for details of the supported syntax for <search-terms>. Supported options for search include --format=(json|text) Presents the results in either JSON or plain-text (default). --output=(summary|threads|messages|files|tags) summary Output a summary of each thread with any message matching the search terms. The summary includes the thread ID, date, the num- ber of messages in the thread (both the number matched and the total number), the authors of the thread and the subject. threads Output the thread IDs of all threads with any message matching the search terms, either one per line (--format=text) or as a JSON array (--format=json). messages Output the message IDs of all messages matching the search terms, either one per line (--format=text) or as a JSON array (--format=json). files Output the filenames of all messages matching the search terms, either one per line (--format=text) or as a JSON array (--for- mat=json). tags Output all tags that appear on any message matching the search terms, either one per line (--format=text) or as a JSON array (--format=json). --sort=(newest-first|oldest-first) This option can be used to present results in either chronological order (oldest-first) or reverse chronological order (new- est-first). Note: The thread order will be distinct between these two options (beyond being simply reversed). When sorting by oldest-first the threads will be sorted by the oldest message in each thread, but when sorting by newest-first the threads will be sorted by the newest message in each thread. By default, results will be displayed in reverse chronological order, (that is, the newest results will be displayed first). --offset=[-]N Skip displaying the first N results. With the leading '-', start at the Nth result from the end. --limit=N Limit the number of displayed results to N. --exclude=(true|false|flag) Specify whether to omit messages matching search.tag_exclude from the search results (the default) or not. The extra option flag only has an effect when --output=summary In this case all matching threads are returned but the "match count" is the number of matching non-excluded messages in the thread.
