-## `{{` and `}}` for literal `{`/`}` signs. The search engine named
-## `DEFAULT` is used when `url.auto_search` is turned on and something

+## `{{` and `}}` for literal `{`/`}` braces. The following further
+## placeholds are defined to configure how special characters in the
+## search terms are replaced by safe characters (called 'quoting'):
+## * `{}` and `{semiquoted}` quote everything except slashes; this is the
+## most sensible choice for almost all search engines (for the search
+## term `slash/and&` this placeholder expands to `slash/and%26amp`).
+## * `{quoted}` quotes all characters (for `slash/and&` this
+## placeholder expands to `slash%2Fand%26amp`).
+## * `{unquoted}` quotes nothing (for `slash/and&` this placeholder
+## expands to `slash/and&`).
