+Filter Data on Atlas Using Atlas Search 
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For your :pipeline:`$search` queries against data on your :atlas:`Atlas 
+</>` cluster, you can use the :atlas:`Atlas Search </atlas-search>` 
+:ref:`compound-ref` operator ``filter`` option to match or filter 
+documents. Running :pipeline:`$match` after :pipeline:`$search` is less 
+performant than running :pipeline:`$search` with the  
+:ref:`compound-ref` operator ``filter`` option. To learn more about the 
+``filter`` option, see :ref:`compound-ref`.
