.SH NAME
notmuch-search \- search for messages matching the given search terms
.SH SYNOPSIS
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.

+
+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,
+.BR true ,
+prevents excluded messages from matching the search terms.
+
+.B all
+additionally prevents excluded messages from appearing in displayed
+results, in effect behaving as though the excluded messages do not exist.
+
+.B false
+allows excluded messages to match search terms and appear in displayed
+results. Excluded messages are still marked in the relevant outputs.
-Specify whether to omit messages matching search.tag_exclude from the
-search results (the default) or not. The extra option
.B flag
only has an effect when
-.B --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.
+.BR --output=summary .
+The output is almost identical to
+.BR false ,
+but the "match count" is the number of matching non-excluded messages in the
+thread, rather than the number of matching messages.

+.BR \-\-duplicate=N
+
+Effective with
+.BR --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
+.BR folder:
+search prefix. The prefix matches messages based on filenames. This
+option filters filenames of the matching messages.
