-How to search for examples
-==========================
-
-The nearly 300 code :ref:`examples-index` included with the Matplotlib
-source distribution are full-text searchable from the :ref:`search`
-page, but sometimes when you search, you get a lot of results from the
-:ref:`api-index` or other documentation that you may not be interested
-in if you just want to find a complete, free-standing, working piece
-of example code.  To facilitate example searches, we have tagged every
-code example page with the keyword ``codex`` for *code example* which
-shouldn't appear anywhere else on this site except in the FAQ.
-So if you want to search for an example that uses an
-ellipse, :ref:`search` for ``codex ellipse``.
