+ Search prefixes
+
In addition to free text, the following prefixes can be used to force
terms to match against specific portions of an email, (where <brackets>
- indicate user-supplied values):
-
- · from:<name-or-address>
-
- · to:<name-or-address>
-
- · subject:<word-or-quoted-phrase>
-
- · attachment:<word>
-
- · mimetype:<word>
-
- · tag:<tag> (or is:<tag>)
-
- · id:<message-id>
-
- · thread:<thread-id>
-
- · folder:<maildir-folder>
-
- · path:<directory-path> or path:<directory-path>/**
-
- · date:<since>..<until>
-
- · lastmod:<initial-revision>..<final-revision>
-
- · query:<name>
-
- The from: prefix is used to match the name or address of the sender of
- an email message.
-
- The to: prefix is used to match the names or addresses of any recipient
- of an email message, (whether To, Cc, or Bcc).
-
- Any term prefixed with subject: will match only text from the subject
- of an email. Searching for a phrase in the subject is supported by
- including quotation marks around the phrase, immediately following sub-
- ject:.
-
- The attachment: prefix can be used to search for specific filenames (or
- extensions) of attachments to email messages.
-
- The mimetype: prefix will be used to match text from the content-types
- of MIME parts within email messages (as specified by the sender).
-
- For tag: and is: valid tag values include inbox and unread by default
- for new messages added by notmuch new as well as any other tag values
- added manually with notmuch tag.
-
- For id:, message ID values are the literal contents of the Message-ID:
- header of email messages, but without the '<', '>' delimiters.
-
- The thread: prefix can be used with the thread ID values that are genâ
- erated internally by notmuch (and do not appear in email messages).
- These thread ID values can be seen in the first column of output from
- notmuch search
-
- The path: prefix searches for email messages that are in particular
- directories within the mail store. The directory must be specified relâ
- ative to the top-level maildir (and without the leading slash). By
- default, path: matches messages in the specified directory only. The
- "/**" suffix can be used to match messages in the specified directory
- and all its subdirectories recursively. path:"" matches messages in
- the root of the mail store and, likewise, path:** matches all messages.
-
- The folder: prefix searches for email messages by maildir or MH folder.
- For MH-style folders, this is equivalent to path:. For maildir, this
- includes messages in the "new" and "cur" subdirectories. The exact synâ
- tax for maildir folders depends on your mail configuration. For
- maildir++, folder:"" matches the inbox folder (which is the root in
- maildir++), other folder names always start with ".", and nested foldâ
- ers are separated by "."s, such as folder:.classes.topology. For "file
- system" maildir, the inbox is typically folder:INBOX and nested folders
- are separated by slashes, such as folder:classes/topology.
-
- Both path: and folder: will find a message if any copy of that message
- is in the specific directory/folder.
-
- The date: prefix can be used to restrict the results to only messages
- within a particular time range (based on the Date: header) with a range
- syntax of:
-
- date:<since>..<until>
-
- See DATE AND TIME SEARCH below for details on the range expression, and
- supported syntax for <since> and <until> date and time expressions.
-
- The time range can also be specified using timestamps with a syntax of:
-
- <initial-timestamp>..<final-timestamp>
-
- Each timestamp is a number representing the number of seconds since
- 1970-01-01 00:00:00 UTC.
-
- The lastmod: prefix can be used to restrict the result by the database
- revision number of when messages were last modified (tags were
- added/removed or filenames changed). This is usually used in conjuncâ
- tion with the --uuid argument to notmuch search to find messages that
- have changed since an earlier query.
-
- The query: prefix allows queries to refer to previously saved queries
- added with notmuch-config(1). Named queries are only available if notâ

+ indicate user-supplied values).
+
+ If notmuch is built with Xapian Field Processors (see below) some of
+ the prefixes with <regex> forms can be also used to restrict the
+ results to those whose value matches a regular expression (see
+ regex(7)) delimited with //, for example:
+
+ notmuch search 'from:"/bob@.*[.]example[.]com/"'
+
+ body:<word-or-quoted-phrase>
+ Match terms in the body of messages.
+
+ from:<name-or-address> or from:/<regex>/
+ The from: prefix is used to match the name or address of the
+ sender of an email message.
+
+ to:<name-or-address>
+ The to: prefix is used to match the names or addresses of any
+ recipient of an email message, (whether To, Cc, or Bcc).
+
+ subject:<word-or-quoted-phrase> or subject:/<regex>/
+ Any term prefixed with subject: will match only text from the
+ subject of an email. Searching for a phrase in the subject is
+ supported by including quotation marks around the phrase, immeâ
+ diately following subject:.
+
+ attachment:<word>
+ The attachment: prefix can be used to search for specific fileâ
+ names (or extensions) of attachments to email messages.
+
+ mimetype:<word>
+ The mimetype: prefix will be used to match text from the conâ
+ tent-types of MIME parts within email messages (as specified by
+ the sender).
+
+ tag:<tag> or tag:/<regex>/ or is:<tag> or is:/<regex>/
+ For tag: and is: valid tag values include inbox and unread by
+ default for new messages added by notmuch new as well as any
+ other tag values added manually with notmuch tag.
+
+ id:<message-id> or mid:<message-id> or mid:/<regex>/
+ For id: and mid:, message ID values are the literal contents of
+ the Message-ID: header of email messages, but without the '<',
+ '>' delimiters.
+
+ thread:<thread-id>
+ The thread: prefix can be used with the thread ID values that
+ are generated internally by notmuch (and do not appear in email
+ messages). These thread ID values can be seen in the first colâ
+ umn of output from notmuch search
+
+ thread:{<notmuch query>}
+ If notmuch is built with Xapian Field Processors (see below),
+ threads may be searched for indirectly by providing an arbitrary
+ notmuch query in {}. For example, the following returns threads
+ containing a message from mallory and one (not necessarily the
+ same message) with Subject containing the word "crypto".
+
+ % notmuch search 'thread:"{from:mallory}" and thread:"{subject:crypto}"'
+
+ The performance of such queries can vary wildly. To understand
+ this, the user should think of the query thread:{<something>} as
+ expanding to all of the thread IDs which match <something>; notâ
+ much then performs a second search using the expanded query.
+
+ path:<directory-path> or path:<directory-path>/** or path:/<regex>/
+ The path: prefix searches for email messages that are in particâ
+ ular directories within the mail store. The directory must be
+ specified relative to the top-level maildir (and without the
+ leading slash). By default, path: matches messages in the speciâ
+ fied directory only. The "/**" suffix can be used to match mesâ
+ sages in the specified directory and all its subdirectories
+ recursively. path:"" matches messages in the root of the mail
+ store and, likewise, path:** matches all messages.
+
+ path: will find a message if any copy of that message is in the
+ specific directory.
+
+ folder:<maildir-folder> or folder:/<regex>/
+ The folder: prefix searches for email messages by maildir or MH
+ folder. For MH-style folders, this is equivalent to path:. For
+ maildir, this includes messages in the "new" and "cur" subdirecâ
+ tories. The exact syntax for maildir folders depends on your
+ mail configuration. For maildir++, folder:"" matches the inbox
+ folder (which is the root in maildir++), other folder names
+ always start with ".", and nested folders are separated by "."s,
+ such as folder:.classes.topology. For "file system" maildir, the
+ inbox is typically folder:INBOX and nested folders are separated
+ by slashes, such as folder:classes/topology.
+
+ folder: will find a message if any copy of that message is in
+ the specific folder.
+
+ date:<since>..<until> or date:<date>
+ The date: prefix can be used to restrict the results to only
+ messages within a particular time range (based on the Date:
+ header).
+
+ See DATE AND TIME SEARCH below for details on the range expresâ
+ sion, and supported syntax for <since> and <until> date and time
+ expressions.
+
+ The time range can also be specified using timestamps without
+ including the date prefix using a syntax of:
+
+ <initial-timestamp>..<final-timestamp>
+
+ Each timestamp is a number representing the number of seconds
+ since 1970-01-01 00:00:00 UTC. Specifying a time range this way
+ is considered legacy and predates the date prefix.
+
+ lastmod:<initial-revision>..<final-revision>
+ The lastmod: prefix can be used to restrict the result by the
+ database revision number of when messages were last modified
+ (tags were added/removed or filenames changed). This is usually
+ used in conjunction with the --uuid argument to notmuch search
+ to find messages that have changed since an earlier query.
+
+ query:<name>
+ The query: prefix allows queries to refer to previously saved
+ queries added with notmuch-config(1). Named queries are only
+ available if notmuch is built with Xapian Field Processors (see
+ below).
+
+ property:<key>=<value>
+ The property: prefix searches for messages with a particular
+ <key>=<value> property pair. Properties are used internally by
+ notmuch (and extensions) to add metadata to messages. A given
+ key can be present on a given message with several different
+ values. See notmuch-properties(7) for more details.
+
+ User defined prefixes are also supported, see notmuch-config(1) for
+ details.
