     prevent wikilinks added by filters from being scanned properly. But
     no known filter hook does that, so let's not waste time on it.
   * Pass a destpage parameter to the sanitize hook.
+  * The search interface now allows searching for a page by title
+    ("title:foo"), as well as for pages that contain a given link
+    ("link:bar").

+
+If searching is enabled, you can enter search terms in the search field,
+like you'd expect. There are a few special things you can do to constuct
+more powerful searches.
+
+* To match a phrase, enclose it in double quotes.
+* `AND` can be used to search for documents containing two expressions.
+* `OR` can be used to search for documents containing either one of
+  two expressions.
+* Parentheses can be used to build up complicated search expressions. For
+  example, "(foo AND bar) OR (me AND you)"
+* Prefix a search term with "-" to avoid it from appearing in the results.
+  For example, "-discussion" will omit "discussion".
+* To search for a page with a given title, use "title:foo".
+* To search for pages that contain a "bar" link, use "link:bar".
