 The document with ``_id`` equal to ``3`` does not contain the ``students`` field
 since no array element matched the :projection:`$elemMatch` criteria.
 
-:projection:`$elemMatch` with :method:`~cursor.sort()`
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-When the :method:`~db.collection.find()` method includes a
-:method:`~cursor.sort()`, the :method:`~db.collection.find()` method
-applies the :method:`~cursor.sort()` to order the matching documents
-**before** it applies the projection. This is a general rule when sorting
-and projecting, and is discussed in :ref:`sort-with-projection`.
-
-If an array field contains multiple documents with the same field
-name and the :method:`~db.collection.find()` method includes a
-:method:`~cursor.sort()` on that repeating field, the returned
-documents may not reflect the sort order because the
-:method:`~cursor.sort()` was applied to the elements of the array
-before the :projection:`$elemMatch` projection.
-
-An array's sorting value is taken from either its "minimum" or "maximum" value,
-depending on which way the sorting goes. The way that :method:`~cursor.sort()`
-sorts documents containing arrays is described in :ref:`sort-asc-desc`.
-
-The following query includes a :method:`~cursor.sort()` to order
-by descending ``students.age`` field:
-
-.. code-block:: javascript
-
-   db.schools.find(
-                    { zipcode: "63109" },
-                    { students: { $elemMatch: { school: 102 } } }
-                  ).sort( { "students.age": -1 } )
-
-The operation applies the :method:`~cursor.sort()` to order the
-documents that have the field ``zipcode`` equal to ``63109`` and
-then applies the projection. The operation returns the three
-documents in the following order:
-
-.. code-block:: javascript
-
-   { "_id" : 4, "students" : [ { "name" : "barney", "school" : 102, "age" : 7 } ] }
-   { "_id" : 1, "students" : [ { "name" : "john", "school" : 102, "age" : 10 } ] }
-   { "_id" : 3 }
-
-Even though the sort is descending, the younger student is listed first. This
-is because the sort occurred before the older students in Barney's document were
-projected out.
