.. step:: Configure Scout in your application
91+
92+
Ensure that your application is configured to use MongoDB as its
93+
database connection. To learn how to configure MongoDB, see the
94+
:ref:`laravel-quick-start-connect-to-mongodb` section of the Quick Start
95+
guide.
96+
97+
To configure Scout in your application, create a file named
98+
``scout.php`` in your application's ``config`` directory. Paste the
99+
following code into the file to configure Scout:
100+
101+
.. code-block:: php
102+
:caption: config/scout.php
103+
104+
<?php
105+
106+
return [
107+
'driver' => env('SCOUT_DRIVER', 'mongodb'),
108+
'mongodb' => [
109+
'connection' => env('SCOUT_MONGODB_CONNECTION', 'mongodb'),
110+
],
111+
'prefix' => env('SCOUT_PREFIX', 'scout_'),
112+
];
113+
114+
The preceding code specifies the following configuration:
115+
116+
- Uses the value of the ``SCOUT_DRIVER`` environment variable as
117+
the default search driver, or ``mongodb`` if the environment
118+
variable is not set
119+
120+
- Specifies ``scout_`` as the prefix for the collection name of the
121+
searchable collection
122+
123+
Set the following environment variable in your application's
124+
``.env`` file to select ``mongodb`` as the default search driver:
125+
126+
.. code-block:: none
127+
:caption: .env
128+
129+
SCOUT_DRIVER=mongodb
130+
131+
.. tip:: Queueing
132+
133+
When using Scout, consider configuring a queue driver to reduce
134+
response times for your application's web interface. To learn more,
135+
see the `Queuing section
136+
<https://laravel.com/docs/{+laravel-docs-version+}/scout#queueing>`__
137+
of the Laravel Scout documentation and the :ref:`laravel-queues` guide.
138+
139+
.. step:: Create the Atlas Search index
140+
141+
After you configure Scout and set your default search driver, you can
142+
create your searchable collection and search index by running the
143+
following command from your application's root directory:
144+
145+
.. code-block:: bash
146+
147+
php artisan scout:index 'App\Models\Movie'
148+
149+
Because you set MongoDB as the default search driver, the preceding
150+
command creates the search collection with an Atlas Search index in your
151+
MongoDB database. The collection is named ``scout_movies``, based on the prefix
152+
set in the preceding step. The Atlas Search index is named ``scout``
153+
and has the following configuration:
154+
155+
.. code-block:: json
156+
157+
{
158+
"mappings": {
159+
"dynamic": true
160+
}
161+
}
162+
163+
.. note::
164+
165+
MongoDB can take up to a minute to create and finalize
166+
an Atlas Search index, so the ``scout:index`` command might not
167+
return a success message immediately.
168+
169+
.. step:: Import data into the searchable collection
170+
171+
You can use Scout to replicate data from a source collection into a
172+
searchable collection. The following command replicates and indexes data
173+
from the ``movies`` collection into the ``scout_movies`` collection
174+
created in the preceding step:
175+
176+
.. code-block:: bash
177+
178+
php artisan scout:import 'App\Models\Movie'
179+
180+
The documents are automatically indexed for Atlas Search queries.
181+
182+
.. tip:: Select Fields to Import
183+
184+
You might not need all the fields from your source documents in your
185+
searchable collection. Limiting the fields you replicate can improve
186+
your application's speed and performance.

select only the ``plot`` and ``title`` fields for replication:
