8 **notmuch** **count** [option ...] <*search-term*> ...
10 **notmuch** **dump** [--format=(batch-tag|sup)] [--] [--output=<*file*>] [--] [<*search-term*> ...]
12 **notmuch** **reindex** [option ...] <*search-term*> ...
14 **notmuch** **search** [option ...] <*search-term*> ...
16 **notmuch** **show** [option ...] <*search-term*> ...
18 **notmuch** **tag** +<*tag*> ... -<*tag*> [--] <*search-term*> ...
23 Several notmuch commands accept a common syntax for search terms.
25 The search terms can consist of free-form text (and quoted phrases)
26 which will match all messages that contain all of the given
27 terms/phrases in the body, the subject, or any of the sender or
30 As a special case, a search string consisting of exactly a single
31 asterisk ("\*") will match all messages.
36 In addition to free text, the following prefixes can be used to force
37 terms to match against specific portions of an email, (where <brackets>
38 indicate user-supplied values).
40 If notmuch is built with **Xapian Field Processors** (see below) some
41 of the prefixes with <regex> forms can be also used to restrict the
42 results to those whose value matches a regular expression (see
43 **regex(7)**) delimited with //, for example::
45 notmuch search 'from:/bob@.*[.]example[.]com/'
47 from:<name-or-address> or from:/<regex>/
48 The **from:** prefix is used to match the name or address of
49 the sender of an email message.
52 The **to:** prefix is used to match the names or addresses of any
53 recipient of an email message, (whether To, Cc, or Bcc).
55 subject:<word-or-quoted-phrase> or subject:/<regex>/
56 Any term prefixed with **subject:** will match only text from the
57 subject of an email. Searching for a phrase in the subject is
58 supported by including quotation marks around the phrase,
59 immediately following **subject:**.
62 The **attachment:** prefix can be used to search for specific
63 filenames (or extensions) of attachments to email messages.
66 The **mimetype:** prefix will be used to match text from the
67 content-types of MIME parts within email messages (as specified by
70 tag:<tag> or tag:/<regex>/ or is:<tag> or is:/<regex>/
71 For **tag:** and **is:** valid tag values include **inbox** and
72 **unread** by default for new messages added by **notmuch new** as
73 well as any other tag values added manually with **notmuch tag**.
75 id:<message-id> or mid:<message-id> or mid:/<regex>/
76 For **id:** and **mid:**, message ID values are the literal
77 contents of the Message-ID: header of email messages, but without
78 the '<', '>' delimiters.
81 The **thread:** prefix can be used with the thread ID values that
82 are generated internally by notmuch (and do not appear in email
83 messages). These thread ID values can be seen in the first column
84 of output from **notmuch search**
86 path:<directory-path> or path:<directory-path>/** or path:/<regex>/
87 The **path:** prefix searches for email messages that are in
88 particular directories within the mail store. The directory must
89 be specified relative to the top-level maildir (and without the
90 leading slash). By default, **path:** matches messages in the
91 specified directory only. The "/\*\*" suffix can be used to match
92 messages in the specified directory and all its subdirectories
93 recursively. **path:""** matches messages in the root of the mail
94 store and, likewise, **path:\*\*** matches all messages.
96 **path:** will find a message if *any* copy of that message is in
97 the specific directory.
99 folder:<maildir-folder> or folder:/<regex>/
100 The **folder:** prefix searches for email messages by maildir or
101 MH folder. For MH-style folders, this is equivalent to
102 **path:**. For maildir, this includes messages in the "new" and
103 "cur" subdirectories. The exact syntax for maildir folders depends
104 on your mail configuration. For maildir++, **folder:""** matches
105 the inbox folder (which is the root in maildir++), other folder
106 names always start with ".", and nested folders are separated by
107 "."s, such as **folder:.classes.topology**. For "file system"
108 maildir, the inbox is typically **folder:INBOX** and nested
109 folders are separated by slashes, such as
110 **folder:classes/topology**.
112 **folder:** will find a message if *any* copy of that message is
113 in the specific folder.
115 date:<since>..<until> or date:<date>
116 The **date:** prefix can be used to restrict the results to only
117 messages within a particular time range (based on the Date:
120 See **DATE AND TIME SEARCH** below for details on the range
121 expression, and supported syntax for <since> and <until> date and
124 The time range can also be specified using timestamps without
125 including the date prefix using a syntax of:
127 <initial-timestamp>..<final-timestamp>
129 Each timestamp is a number representing the number of seconds
130 since 1970-01-01 00:00:00 UTC. Specifying a time range this way
131 is considered legacy and predates the date prefix.
133 lastmod:<initial-revision>..<final-revision>
134 The **lastmod:** prefix can be used to restrict the result by the
135 database revision number of when messages were last modified (tags
136 were added/removed or filenames changed). This is usually used in
137 conjunction with the **--uuid** argument to **notmuch search** to
138 find messages that have changed since an earlier query.
141 The **query:** prefix allows queries to refer to previously saved
142 queries added with **notmuch-config(1)**. Named queries are only
143 available if notmuch is built with **Xapian Field Processors**
146 property:<key>=<value>
147 The **property:** prefix searches for messages with a particular
148 <key>=<value> property pair. Properties are used internally by
149 notmuch (and extensions) to add metadata to messages. A given key
150 can be present on a given message with several different values.
151 See **notmuch-properties(7)** for more details.
156 In addition to individual terms, multiple terms can be combined with
157 Boolean operators (**and**, **or**, **not**, and **xor**). Each term
158 in the query will be implicitly connected by a logical AND if no
159 explicit operator is provided (except that terms with a common prefix
160 will be implicitly combined with OR). The shorthand '-<term>' can be
161 used for 'not <term>' but unfortunately this does not work at the
162 start of an expression. Parentheses can also be used to control the
163 combination of the Boolean operators, but will have to be protected
164 from interpretation by the shell, (such as by putting quotation marks
165 around any parenthesized expression).
167 In addition to the standard boolean operators, Xapian provides several
168 operators specific to text searching.
172 notmuch search term1 NEAR term2
174 will return results where term1 is within 10 words of term2. The
175 threshold can be set like this:
179 notmuch search term1 NEAR/2 term2
185 notmuch search term1 ADJ term2
187 will return results where term1 is within 10 words of term2, but in the
188 same order as in the query. The threshold can be set the same as with
193 notmuch search term1 ADJ/7 term2
199 **Stemming** in notmuch means that these searches
203 notmuch search detailed
204 notmuch search details
205 notmuch search detail
207 will all return identical results, because Xapian first "reduces" the
208 term to the common stem (here 'detail') and then performs the search.
210 There are two ways to turn this off: a search for a capitalized word
211 will be performed unstemmed, so that one can search for "John" and not
212 get results for "Johnson"; phrase searches are also unstemmed (see
213 below for details). Stemming is currently only supported for
214 English. Searches for words in other languages will be performed unstemmed.
219 It is possible to use a trailing '\*' as a wildcard. A search for
220 'wildc\*' will match 'wildcard', 'wildcat', etc.
223 Boolean and Probabilistic Prefixes
224 ----------------------------------
226 Xapian (and hence notmuch) prefixes are either **boolean**, supporting
227 exact matches like "tag:inbox" or **probabilistic**, supporting a more
228 flexible **term** based searching. Certain **special** prefixes are
229 processed by notmuch in a way not strictly fitting either of Xapian's
230 built in styles. The prefixes currently supported by notmuch are as
234 **tag:**, **id:**, **thread:**, **folder:**, **path:**, **property:**
236 **to:**, **attachment:**, **mimetype:**
238 **from:**, **query:**, **subject:**
243 In general Xapian distinguishes between lists of terms and
244 **phrases**. Phrases are indicated by double quotes (but beware you
245 probably need to protect those from your shell) and insist that those
246 unstemmed words occur in that order. One useful, but initially
247 surprising feature is that the following are equivalent ways to write
255 Both parenthesised lists of terms and quoted phrases are ok with
256 probabilistic prefixes such as **to:**, **from:**, and **subject:**. In particular
266 subject:pizza and subject:free
268 Both of these will match a subject "Free Delicious Pizza" while
279 notmuch understands a variety of standard and natural ways of expressing
280 dates and times, both in absolute terms ("2012-10-24") and in relative
281 terms ("yesterday"). Any number of relative terms can be combined ("1
282 hour 25 minutes") and an absolute date/time can be combined with
283 relative terms to further adjust it. A non-exhaustive description of the
284 syntax supported for absolute and relative terms is given below.
289 date:<since>..<until>
291 The above expression restricts the results to only messages from <since>
292 to <until>, based on the Date: header.
294 <since> and <until> can describe imprecise times, such as "yesterday".
295 In this case, <since> is taken as the earliest time it could describe
296 (the beginning of yesterday) and <until> is taken as the latest time it
297 could describe (the end of yesterday). Similarly, date:january..february
298 matches from the beginning of January to the end of February.
300 If specifying a time range using timestamps in conjunction with the
301 date prefix, each timestamp must be preceded by @ (ASCII hex 40). As
302 above, each timestamp is a number representing the number of seconds
303 since 1970-01-01 00:00:00 UTC. For example:
305 date:@<initial-timestamp>..@<final-timestamp>
307 date:<expr>..! can be used as a shorthand for date:<expr>..<expr>. The
308 expansion takes place before interpretation, and thus, for example,
309 date:monday..! matches from the beginning of Monday until the end of
311 With **Xapian Field Processor** support (see below), non-range
312 date queries such as date:yesterday will work, but otherwise
313 will give unexpected results; if in doubt use date:yesterday..!
315 Currently, we do not support spaces in range expressions. You can
316 replace the spaces with '\_', or (in most cases) '-', or (in some cases)
317 leave the spaces out altogether. Examples in this man page use spaces
320 Open-ended ranges are supported (since Xapian 1.2.1), i.e. it's possible
321 to specify date:..<until> or date:<since>.. to not limit the start or
322 end time, respectively. Pre-1.2.1 Xapian does not report an error on
323 open ended ranges, but it does not work as expected either.
325 Relative date and time
326 ----------------------
329 (years\|months\|weeks\|days\|hours\|hrs\|minutes\|mins\|seconds\|secs)
332 All refer to past, can be repeated and will be accumulated.
334 Units can be abbreviated to any length, with the otherwise ambiguous
335 single m being m for minutes and M for months.
337 Number can also be written out one, two, ..., ten, dozen, hundred.
338 Additionally, the unit may be preceded by "last" or "this" (e.g., "last
339 week" or "this month").
341 When combined with absolute date and time, the relative date and time
342 specification will be relative from the specified absolute date and
345 Examples: 5M2d, two weeks
347 Supported absolute time formats
348 -------------------------------
350 - H[H]:MM[:SS] [(am\|a.m.\|pm\|p.m.)]
352 - H[H] (am\|a.m.\|pm\|p.m.)
362 - Examples: 17:05, 5pm
364 Supported absolute date formats
365 -------------------------------
379 - D[D][(st\|nd\|rd\|th)] Mon[thname] [YYYY]
381 - Mon[thname] D[D][(st\|nd\|rd\|th)] [YYYY]
385 Month names can be abbreviated at three or more characters.
387 Weekday names can be abbreviated at three or more characters.
389 Examples: 2012-07-31, 31-07-2012, 7/31/2012, August 3
398 Some time zone codes, e.g. UTC, EET.
400 XAPIAN FIELD PROCESSORS
401 =======================
403 Certain optional features of the notmuch query processor rely on the
404 presence of the Xapian field processor API. You can determine if your
405 notmuch was built against a sufficiently recent version of Xapian by running
409 % notmuch config get built_with.field_processor
411 Currently the following features require field processor support:
413 - non-range date queries, e.g. "date:today"
414 - named queries e.g. "query:my_special_query"
415 - regular expression searches, e.g. "subject:/^\\[SPAM\\]/"
