You can also call the ``ElemMatch()`` method to find documents that have an
array field that contains at least one element that matches a specified search
criteria. The following example returns documents that contain the value

.. code-block:: csharp
:copyable: true

var builder = Builders<Flower>.Filter;
var filter = builder.ElemMatch(f => f.Season, s => s == "Summer");

To learn more about array operators, see the :manual:`Array Query Operators
