Я использую Elasticsearch-PHP [6.0]
У меня есть индекс products, где у меня есть название продуктов, предлагающих фразу.

Настройка индекса

Параметры запроса 

$params = [
    'index' => 'products',
    'body' => [
        "text" => fortune,
        "simple_phrase" => [

                ]
            ]
        ]
    ]
];  
$response = $client->search($params);

Ошибка

Вам просто не хватает ключевого слова suggest: 

$params = [
    'index' => 'products',
    'body' => [
      "suggest" => [                               <-- add this
        "text" => fortune,
        "simple_phrase" => [
            "phrase" => [
                "field" => "title.trigram",
                "size" => 1,
                "direct_generator" => [ 
                    [
                        "field" => "title.trigram",
                        "suggest_mode" => "always"
                    ],
                    [
                        "field" => "title.reverse",
                        "suggest_mode" => "always",
                        "pre_filter" => "reverse",
                        "post_filter" => "reverse"
                    ]
                ]
            ]
        ]
      ]                                            <-- and this
    ]
];  
$response = $client->search($params);
