+instances:
+
+=for comment
+AUTO-GENERATED-SEARCH-TERMS-BEGIN
+
+  s:        match within Subject  e.g. s:"a quick brown fox"
+  d:        match date-time range, git "approxidate" formats supported
+            Open-ended ranges such as `d:last.week..' and
+            `d:..2.days.ago' are supported

+  nq:       match non-quoted text within message body
+  q:        match quoted text within message body
+  n:        match filename of attachment(s)

+  c:        match within the Cc header
+  f:        match within the From header

+  dfctx:    match diff context lines
+  dfpre:    match pre-image git blob ID
+  dfpost:   match post-image git blob ID
+  dfblob:   match either pre or post-image git blob ID
+  patchid:  match `git patch-id --stable' output
+  rt:       match received time, like `d:' if sender's clock was correct

+
+Additional search prefixes which only affect the local lei/store:
+
+  L:       match the given label
+  kw:      match the given keywords
+
+See L<lei-tag(1)> for more info on labels and keywords.
+
+Most prefixes are probabilistic, meaning they support stemming
+and wildcards (C<*>).  Ranges (such as C<d:>) and boolean prefixes
+do not support stemming or wildcards.
+The upstream Xapian query parser documentation fully explains
+the query syntax: L<https://xapian.org/docs/queryparser.html>
+
+=head1 TIPS
+
+C<-f reply> is intended to aid in turning a cover letter
+into a reply (since using C<git format-patch --in-reply-to=...>
+is tedious).  Results (including "From " lines) should be edited
+and trimmed in your favorite C<$EDITOR> before sending.
