notmuch-search
==============
SYNOPSIS
========
**notmuch** **search** [*option* ...] <*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**\ \|\ **sexp**\ \|\ **text**\ \|\ **text0**)
Presents the results in either JSON, S-Expressions, newline
character separated plain-text (default), or null character
separated plain-text (compatible with **xargs(1)** -0 option
where available).
``--format-version=N``
Use the specified structured output format version. This is
intended for programs that invoke **notmuch(1)** internally. If
omitted, the latest supported version will be used.
``--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 number 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), separated by null characters
(--format=text0), as a JSON array (--format=json), or an
S-Expression list (--format=sexp).
**messages**
Output the message IDs of all messages matching the search
terms, either one per line (--format=text), separated by
null characters (--format=text0), as a JSON array
(--format=json), or as an S-Expression list (--format=sexp).
**files**
Output the filenames of all messages matching the search
terms, either one per line (--format=text), separated by
null characters (--format=text0), as a JSON array
(--format=json), or as an S-Expression list (--format=sexp).
Note that each message may have multiple filenames
associated with it. All of them are included in the output
(unless limited with the --duplicate=N option). This may
be particularly confusing for **folder:** or **path:**
searches in a specified directory, as the messages may
have duplicates in other directories that are included in
the output, although these files alone would not match the
search.
**tags**
Output all tags that appear on any message matching the
search terms, either one per line (--format=text), separated
by null characters (--format=text0), as a JSON array
(--format=json), or as an S-Expression list (--format=sexp).
``--sort=``\ (**newest-first**\ \|\ **oldest-first**)
This option can be used to present results in either
chronological order (**oldest-first**) or reverse chronological
order (**newest-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|all|flag)``
A message is called "excluded" if it matches at least one tag in
search.tag\_exclude that does not appear explicitly in the
search terms. This option specifies whether to omit excluded
messages in the search process.
The default value, **true**, prevents excluded messages from
matching the search terms.
**all** additionally prevents excluded messages from appearing
in displayed results, in effect behaving as though the excluded
messages do not exist.
**false** allows excluded messages to match search terms and
appear in displayed results. Excluded messages are still marked
in the relevant outputs.
**flag** only has an effect when ``--output=summary``. The
output is almost identical to **false**, but the "match count"
is the number of matching non-excluded messages in the thread,
rather than the number of matching messages.
``--duplicate=N``
Effective with ``--output=files``, output the Nth filename
associated with each message matching the query (N is 1-based).
If N is greater than the number of files associated with the
message, don't print anything.
Note that this option is orthogonal with the **folder:** search
prefix. The prefix matches messages based on filenames. This
option filters filenames of the matching messages.
EXIT STATUS
===========
This command supports the following special exit status codes
``20``
The requested format version is too old.
``21``
The requested format version is too new.
