Atlas Search Index Management
150+
-----------------------------
151+
152+
The following sections contain code examples that describe how to manage Atlas Search indexes.
153+
To learn more about Atlas Search indexes, see the :ref:`Atlas Search Indexes <cpp-atlas-search-index>` guide.
154+
155+
Create Search Index
156+
~~~~~~~~~~~~~~~~~~~
157+
158+
The following code shows how to create an Atlas Search index that dynamically indexes all supported fields in the specified collection:
159+
160+
.. io-code-block::
161+
:copyable: true
162+
163+
.. input:: /includes/usage-examples/index-code-examples.cpp

167+
:dedent:
168+
169+
.. output::
170+
:language: cli
171+
:visible: false
172+
173+
New index name: searchIndexName
174+
175+
List Search Indexes
176+
~~~~~~~~~~~~~~~~~~~
177+
178+
The following code prints a list of Atlas Search indexes in the specified collection:
179+
180+
.. literalinclude:: /includes/usage-examples/index-code-examples.cpp
181+
:start-after: start-list-search-indexes
182+

183+
:language: cpp
184+
:copyable:
185+
:dedent:
186+
187+
Update Search Indexes
188+
~~~~~~~~~~~~~~~~~~~~~
189+
190+
The following code updates an existing Atlas Search index with the specified new index definition:
191+
192+
.. literalinclude:: /includes/usage-examples/index-code-examples.cpp
193+
:start-after: start-update-search-index
