Я хочу создать секретный портал, где я использую Elasticsearch 7.3 для хранения данных о продукте, чтобы я мог быстро получать результаты поиска в списке и выполнять автозаполнение.Я хочу получить результат, как у флипкарта или олкса.например, «холодильник в Ac» или «Джинсы для мужчин», «Джинсы для женщин», «Джинсы в левисе».Согласно моему исследованию эластичного поиска, я сначала создал индекс с помощью Analyzer и соответственно установил Mapper для полей.Ниже приведен мой анализатор и фрагмент кода.
Я использую PHP 5.6 с Elasticsearch 7.3 на Ubuntu 16.03
Анализатор и создаю индекс:

Может кто-нибудь направить меня сюда, пожалуйста?Как я могу достичь своих требований?Что-нибудь, я должен изменить в моем анализаторе?Как инициировать поисковый запрос для автозаполнения результата, как я уже упоминал выше?так что если в строке поиска я наберу 'Fr' или 'fridge' или 'freeze' или 'frige', я должен получить все результаты, исправив опечатку автоматически и перечислив все результаты.
