+ Notmuch restore supports two plain text dump formats, both with one
+ message-id per line, followed by a list of tags.
+
+ sup The sup dump file format is specifically chosen to be compati-
+ ble with the format of files produced by sup-dump. So if
+ you've previously been using sup for mail, then the notmuch
+ restore command provides you a way to import all of your tags
+ (or labels as sup calls them). Each line has the following
+ form
+
+ <message-id> ( <tag> ... )
+
+ with zero or more tags are separated by spaces. Note that (mal-
+ formed) message-ids may contain arbitrary non-null characters.
+ Note also that tags with spaces will not be correctly restored
+ with this format.
+
+ batch-tag
+
+ The batch-tag dump format is intended to more robust against
+ malformed message-ids and tags containing whitespace or non-
+ ascii(7) characters. Each line has the form
+
+ +<encoded-tag> +<encoded-tag> ... -- id:<quoted-message-id>
+
+ Tags are hex-encoded by replacing every byte not matching the
+ regex [A-Za-z0-9@=.,_+-] with %nn where nn is the two digit hex
+ encoding. The message ID is a valid Xapian query, quoted using
+ Xapian boolean term quoting rules: if the ID contains whites-
+ pace or a close paren or starts with a double quote, it must be
+ enclosed in double quotes and double quotes inside the ID must
+ be doubled. The astute reader will notice this is a special
+ case of the batch input format for notmuch-tag(1); note that
+ the single message-id query is mandatory for notmuch-
+ restore(1).
+
+ With no search terms, a dump of all messages in the database will
+ be generated. A "--" argument instructs notmuch that the remaining
+ arguments are search terms.
+
+ See notmuch-search-terms(7) for details of the supported syntax for
+ <search-terms>.
