+Consider an application that captures user-defined data under the
+``userMetadata`` field and supports querying against that data:
+
+.. code-block:: javascript
+   :copyable: false
+
+   { "userMetadata" : { "likes" : [ "dogs", "cats" ] } }
+   { "userMetadata" : { "dislikes" : "pickles" } }
+   { "userMetadata" : { "age" : 45 } }
+   { "userMetadata" : "inactive" }
+
+Administrators want to create indexes to support queries on any
+subfield of ``userMetadata``.
+
+A wildcard index on ``userMetadata``
+can support single-field queries on ``userMetadata``,
+``userMetadata.likes``, ``userMetadata.dislikes``, and
+``userMetadata.age``:
+
+.. code-block:: bash
+
+   db.userData.createIndex( { "userMetadata.$**" : 1 } )
+
+The index can support the following queries:
+
+.. code-block:: bash
+   :copyable: false
+
+   db.userData.find({ "userMetadata.likes" : "dogs" })
+   db.userData.find({ "userMetadata.dislikes" : "pickles" })
+   db.userData.find({ "userMetadata.age" : { $gt : 30 } })
+   db.userData.find({ "userMetadata" : "inactive" })
+
+A non-wildcard index on ``userMetadata`` can only support queries on
+values of ``userMetadata``.
+
+.. important::
+
+   Wildcard indexes are not designed to replace workload-based index
+   planning. For more information on creating indexes to support
+   queries, see :ref:`create-indexes-to-support-queries`. For 
+   complete documentation on wildcard index limitations, see 
+   :ref:`wildcard-index-restrictions`.
+
+
+The :binary:`~bin.mongod` 
+:ref:`featureCompatibilityVersion <view-fcv>` must be ``4.2`` to
+create wildcard indexes. For instructions on setting the fCV, see 
+:ref:`Setting the fCV <set-fcv>`.
