Elasticsearch not returning partial results

I am using Laravel 5.1 and the mustafaaloko/elasticquent5 package (found here).

But when trying to return results, I can only get results when searching for the exact word. If I try to search part of the word, it returns nothing.

I am using Profile::addAllToIndex(); and dd(Profile::search(Input::get('search_term')));

My config looks like this:

<?php

return array(

    /*
    |--------------------------------------------------------------------------
    | Custom Elasticsearch Client Configuration
    |--------------------------------------------------------------------------
    |
    | This array will be passed to the Elasticsearch client.
    | See configuration options here:
    |
    | http://ift.tt/1rOUwKt
    */

    'config' => [
        'hosts'     => ['ahp.dev:9200'],
        'logging'   => true,
        'logPath'   => storage_path() . '/logs/elasticsearch.log',
        'logLevel'  => Monolog\Logger::WARNING,
    ],

    /*
    |--------------------------------------------------------------------------
    | Default Index Name
    |--------------------------------------------------------------------------
    |
    | This is the index name that Elastiquent will use for all
    | Elastiquent models.
    */

    'default_index' => 'default',

);
