+Overview
+--------
+
+In this guide, you can learn how to use the **Atlas Search** feature on a collection.
+Atlas Search enables you to perform full-text searches on collections hosted on MongoDB
+Atlas. Atlas Search indexes specify the behavior of the search and which fields to index.
+
+Run an Atlas Search Query
+-------------------------
+
+This section shows how to create an aggregation pipeline to run an
+Atlas Search on a collection. You can use ``Aggregates.search`` builder to
+create a ``$search`` pipeline stage and specify your search. Then, call
+the ``aggregate()`` method and pass your pipeline as a parameter.
+
+.. tip:: 
+
+   To learn more about aggregation operations and builders, see the :ref:`java-aggregation`
+   guide. 
+
+Before running an Atlas Search query, you must create an Atlas Search index
+on your collection. To learn how to programmatically create an Atlas Search
+index, see the :ref:`java-search-indexes` section in the Indexes guide. 
+
+Sample Data
+~~~~~~~~~~~
+
+The example in this section uses the ``movies`` collection in the ``sample_mflix``
+database from the :atlas:`Atlas sample datasets </sample-data>`. To learn how to
+create a free MongoDB Atlas cluster and load the sample datasets, see the
+:atlas:`Get Started with Atlas </getting-started>` guide.
+
+Atlas Search Example
+~~~~~~~~~~~~~~~~~~~~
+
+This example performs an Atlas Search query by calling the
+``aggregate()`` method and passing the following pipeline stages:
+
+- ``Aggregates.search``: Specifies a search query for documents in which
+  the ``title`` field contains the word ``"Alabama"``
+- ``Aggregates.project``: Projects the ``title`` field of each matching document

+      {"_id": {"$oid": "..."}, "title": "Crazy in Alabama"}
+      {"_id": {"$oid": "..."}, "title": "Sweet Home Alabama"}
