Configuration
Below is an example of Dexter's default settings. Add it to your ExpressionEngine system/user/config/config.php file. You do not have to copy the entire array. Array keys not found in your config.php file will fall back to the default values. Your config.php file should look similar to this:
<?php
$config['dexter'] = [
'provider' => 'meilisearch',
...
];The full default config.
<?php
/**
* DO NOT EDIT THIS FILE DIRECTLY.
*
* Copy this file to your /config directory and rename it to dexter.php
* to override the default settings. You can remove any settings you don't want to change,
* and they will fall back to the defaults defined here.
