.SH NAME
notmuch-sexp-queries \- s-expression syntax for notmuch queries
.SH SYNOPSIS
.sp
\fBnotmuch\fP \fIsubcommand\fP \fB\-\-query=sexp\fP [option ...]  \fB\-\-\fP \(aq(and (to santa) (date december))\(aq
.SH DESCRIPTION
.sp
Notmuch supports an alternative query syntax based on \X'tty: link https://en.wikipedia.org/wiki/S-expression'\fI\%S\-expressions\fP\X'tty: link' . It can be selected
with the command line \fB\-\-query=sexp\fP or with the appropriate option
to the library function \fBnotmuch_query_create_with_syntax()\fP\&.
Support for this syntax is currently optional, you can test if your
build of notmuch supports it with

.SS S\-EXPRESSIONS
.sp
An \fIs\-expression\fP is either an atom, or list of whitespace delimited
s\-expressions inside parentheses. Atoms are either
.sp
\fIbasic value\fP
.INDENT 0.0
.INDENT 3.5
A basic value is an unquoted string containing no whitespace, double quotes, or
parentheses.
.UNINDENT
.UNINDENT
.sp
\fIquoted string\fP
.INDENT 0.0
.INDENT 3.5
Double quotes (\(dq) delimit strings possibly containing whitespace
or parentheses. These can contain double quote characters by
escaping with backslash. E.g. \fB\(dqthis is a quote \e\(dq\(dq\fP\&.
.UNINDENT
.UNINDENT
.SS S\-EXPRESSION QUERIES
.sp
An s\-expression query is either an atom, the empty list, or a
\fIcompound query\fP consisting of a prefix atom (first element) defining
a \fIfield\fP, \fIlogical operation\fP, or \fImodifier\fP, and 0 or more
subqueries.
.sp

.INDENT 0.0
.INDENT 3.5
\(dq*\(dq matches any non\-empty string in the current field.
.UNINDENT
.UNINDENT
.sp
\fB()\fP
.INDENT 0.0
.INDENT 3.5
The empty list matches all messages
.UNINDENT
.UNINDENT
.sp
\fIterm\fP
.INDENT 0.0
.INDENT 3.5
Match all messages containing \fIterm\fP, possibly after stemming or
phrase splitting. For discussion of stemming in notmuch see
\fI\%notmuch\-search\-terms\fP\&. Stemming only applies to unquoted
terms (basic values) in s\-expression queries.  For information on
phrase splitting see \fI\%FIELDS\fP\&.

.INDENT 0.0
.INDENT 3.5
Restrict the queries \fIq\fP\s-2\d1\u\s0 to \fIq\fP\s-2\dn\u\s0 to \fIfield\fP, and combine with \fIand\fP
(for most fields) or \fIor\fP\&. See \fI\%FIELDS\fP for more information.

.INDENT 0.0
.INDENT 3.5
Combine queries \fIq\fP\s-2\d1\u\s0 to \fIq\fP\s-2\dn\u\s0\&. Currently supported operators are
\fBand\fP, \fBor\fP, and \fBnot\fP\&. \fB(not\fP \fIq\fP\s-2\d1\u\s0 ... \fIq\fP\s-2\dn\u\s0 \fB)\fP is equivalent
to \fB(and (not\fP \fIq\fP\s-2\d1\u\s0 \fB) ... (not\fP \fIq\fP\s-2\dn\u\s0 \fB))\fP\&.

.INDENT 0.0
.INDENT 3.5
Combine queries \fIq\fP\s-2\d1\u\s0 to \fIq\fP\s-2\dn\u\s0, and reinterpret the result (e.g. as a regular expression).
See \fI\%MODIFIERS\fP for more information.

.INDENT 0.0
.INDENT 3.5
Define saved query with parameter substitution. The syntax is
recognized only in saved s\-expression queries (see \fBsquery.*\fP in
\fI\%notmuch\-config\fP). Parameter names in \fBbody\fP must be
prefixed with \fB,\fP to be expanded (see \fI\%MACRO EXAMPLES\fP).
Macros may refer to other macros, but only to their own
parameters [1]\&.
.UNINDENT
.UNINDENT
.SS FIELDS
.sp
\fIFields\fP [2]
correspond to attributes of mail messages. Some are inherent (and
immutable) like \fBsubject\fP, while others \fBtag\fP and \fBproperty\fP are
settable by the user.  Each concrete field in
\fI\%the table below\fP
is discussed further under \(dqSearch prefixes\(dq in
\fI\%notmuch\-search\-terms\fP\&. The row \fIuser\fP refers to user defined
fields, described in \fI\%notmuch\-config\fP\&.
.sp
Most fields are either \fIphrase fields\fP [3] (which match
sequences of words), or \fIterm fields\fP [4] (which match exact
strings). \fIPhrase splitting\fP breaks the term (basic value or quoted
string) into words, ignore punctuation. Phrase splitting is applied to
terms in phrase (probabilistic) fields. Both phrase splitting and
stemming apply only in phrase fields.
.sp
Each term or phrase field has an associated combining operator
(\fBand\fP or \fBor\fP) used to combine the queries from each element of
the tail of the list. This is generally \fBor\fP for those fields where
a message has one such attribute, and \fBand\fP otherwise.
.sp
Term or phrase fields can contain arbitrarily complex queries made up
from terms, operators, and modifiers, but not other fields.
.sp
Range fields take one or two arguments specifying lower and upper
bounds.  One argument is interpreted as identical upper and lower
bounds. Either upper or lower bound may be specified as \fB\(dq\(dq\fP or
\fB*\fP to specify the lowest possible lower bound or highest possible
upper bound.
.sp
\fBlastmod\fP ranges support negative arguments, interpreted relative to
the most recent database revision (see \fI\%count \-\-lastmod\fP).

Technically macros implement lazy evaluation and
lexical scope. There is one top level scope
containing all macro definitions, but all
parameter definitions are local to a given macro.

a.k.a. probabilistic prefixes

a.k.a. boolean prefixes
.IP [5] 5
Due to the implementation of phrase fields in Xapian,
regex queries could only match individual words.
.IP [6] 5
Due to the way \fBbody\fP is implemented in notmuch,
this modifier is not supported in the \fBbody\fP field.
.IP [7] 5
Due to the way recursive \fBpath\fP queries are implemented
in notmuch, this modifier is not supported in the
\fBpath\fP field.
