+Supported fields are: date, count, authors, subject, tags.
 For example:
-	(setq notmuch-search-result-format \(\(\"authors\" . \"%-40s\"\)
-					     \(\"subject\" . \"%s\"\)\)\)
+    (setq notmuch-search-result-format

+            (\"subject\" . \"%s\")))

 Line breaks are permitted in format strings (though this is

 \"authors\" field will get elided if the authors list is long;
 place it instead at the beginning of the following field.  To
 enter a line break when setting this variable with setq, use \\n.
 To enter a line break in customize, press \\[quoted-insert] C-j."
