+# Search
+
+Plugins can define and register their own models to extend NetBox's core search functionality. Typically, a plugin will include a file named `search.py`, which holds all search indexes for its models (see the example below).
+
+```python
+# search.py
+from netbox.search import SearchMixin
+from .filters import MyModelFilterSet
+from .tables import MyModelTable
+from .models import MyModel
+
+class MyModelIndex(SearchMixin):
+    model = MyModel
+    queryset = MyModel.objects.all()
+    filterset = MyModelFilterSet
+    table = MyModelTable
+    url = 'plugins:myplugin:mymodel_list'
+```
+
+To register one or more indexes with NetBox, define a list named `indexes` at the end of this file:
+
+```python
+indexes = [MyModelIndex]
+```
+
+!!! tip
+    The path to the list of search indexes can be modified by setting `search_indexes` in the PluginConfig instance.
