+# Search
+
+If you want your plugin models to appear in search results, you will need to create a search index for the models.  Search indexes must be in defined in a search_indexes.py file.
+
+As an example, lets define a search_index for the MyModel object defined before:
+
+```python
+# search_indexes.py
+from .filters import MyFilterSet
+from .tables import MyModelTable
+from .models import MyModel
+from search.models import SearchMixin
+
+
+class MyModelIndex(SearchMixin):
+    model = MyModel
+    queryset = MyModel.objects.all()
+    filterset = MyModelFilterSet
+    table = MyModelTable
+    url = 'plugins:netbox_mymodel:mymodel_list'
+    choice_header = 'MyModel'
+```
+
+All the fields must be defined as follows:
+
+* `model` - The model that will be searched (see: [Models](./models.md)).
+* `queryset` - The queryset on the model that will be passed to the filterset.
+* `filterset` - The filterset for the model that contains the search method (see: [Filters & Filter Sets](./filtersets.md)).
+* `table` - Table that is used in the list view (see:  (see: [Tables](./tables.md)).
+* `url` - URL to the list view to show search results.
+* `choice_header` - The header that will appear in the search drop-down to group menu items together.
