+Expressions
+===========
+
+The ``Doctrine\Common\Collections\Expr\Comparison`` class
+can be used to create expressions to be used with the
+``Doctrine\Common\Collections\Criteria`` class. It has the
+following operator constants:
+
+- ``Comparison::EQ``
+- ``Comparison::NEQ``
+- ``Comparison::LT``
+- ``Comparison::LTE``
+- ``Comparison::GT``
+- ``Comparison::GTE``
+- ``Comparison::IS``
+- ``Comparison::IN``
+- ``Comparison::NIN``
+- ``Comparison::CONTAINS``
+- ``Comparison::MEMBER_OF``
+- ``Comparison::STARTS_WITH``
+- ``Comparison::ENDS_WITH``
+
+The ``Doctrine\Common\Collections\Criteria`` class has the following
+API to be used with expressions:
+
+where
+-----
+
+Sets the where expression to evaluate when this Criteria is searched for.
+
+.. code-block:: php
+    $expr = new Comparison('key', Comparison::EQ, 'value');
+
+    $criteria->where($expr);
+
+andWhere
+--------
+
+Appends the where expression to evaluate when this Criteria is searched for
+using an AND with previous expression.
+
+.. code-block:: php
+    $expr = new Comparison('key', Comparison::EQ, 'value');
+
+    $criteria->andWhere($expr);
+
+orWhere
+-------
+
+Appends the where expression to evaluate when this Criteria is searched for
+using an OR with previous expression.
+
+.. code-block:: php
+    $expr1 = new Comparison('key', Comparison::EQ, 'value1');
+    $expr2 = new Comparison('key', Comparison::EQ, 'value2');
+
+    $criteria->where($expr1);
+    $criteria->orWhere($expr2);
+
+orderBy
+-------
+
+Sets the ordering of the result of this Criteria.
+
+.. code-block:: php
+    $criteria->orderBy(['name' => Criteria::ASC]);
+
+setFirstResult
+--------------
+
+Set the number of first result that this Criteria should return.
+
+.. code-block:: php
+    $criteria->setFirstResult(0);
+
+getFirstResult
+--------------
+
+Gets the current first result option of this Criteria.
+
+.. code-block:: php
+    $criteria->setFirstResult(10);
+
+    echo $criteria->getFirstResult(); // 10
+
+setMaxResults
+-------------
+
+Sets the max results that this Criteria should return.
+
+.. code-block:: php
+    $criteria->setMaxResults(20);
+
+getMaxResults
+-------------
+
+Gets the current max results option of this Criteria.
+
+.. code-block:: php
+    $criteria->setMaxResults(20);
+
+    echo $criteria->getMaxResults(); // 20
