 Use **find operations** to retrieve data from MongoDB. Find operations
 consist of the ``Find()`` and ``FindOne()`` methods.

 Find All Documents
 ~~~~~~~~~~~~~~~~~~
 
 The ``Find()`` method expects you to pass a ``Context`` type and a
 query filter. The method returns *all* documents that match the filter
 as a ``Cursor`` type.
 
-For an example that uses the ``Find()`` method, see the :ref:`golang-find-example`
-section of this page. To learn how to access data by using a cursor, see
-the :ref:`golang-cursor` guide.
-
-Find One Document
-~~~~~~~~~~~~~~~~~
-
-The ``FindOne()`` method expects you to pass a ``Context`` type and a
-query filter. The method returns *the first document* that matches the
-filter as a ``SingleResult`` type.

-For an example that uses the ``FindOne()`` method, see the
-:ref:`golang-find-one-example` section of this page. For an example that
-uses ``FindOne()`` and queries by using a specific ``ObjectId`` value, see
