Добрый день, подскажите, как правильно построить autocomplete для товаров в магазине,  
чтобы при подаче на входе iPhone предлагались не товары а вариации продолжения фразы:  
iphone 6s  
iphone 11 16Gb  
как тут [http://joxi.ru/DmBPz8acJ3Ev5A](http://joxi.ru/DmBPz8acJ3Ev5A)

на данный момент удалось настроить, только продолжение вводимой фразы, при этом если не начат ввод нового слова, предложений не выводится

**форма данных в индексе:**

```auto
      "body" => array:6 [
        "title" => "Холодильник ATLANT ХМ 4423-060 N"
        "title_tags" => array:5 [
          0 => "Холодильник"
          1 => "Холодильник ATLANT"
          2 => "Холодильник ATLANT ХМ"
          3 => "Холодильник ATLANT ХМ 4423-060"
          4 => "Холодильник ATLANT ХМ 4423-060 N"
        ]
        "title_keyword" => " Холодильник ATLANT ХМ 4423-060 N "
        "description" => "линейка: PREMIUM 44 Serie, ШхВхГ: 59.50х196.50х62.50 см, класс энергопотребления A, общий объем 320 л, No Frost"
        "category" => ""
        "brand" => "ATLANT"
      ]
      "index" => "product_index_11232assd5453"
      "type" => "product_11232assd5453"
      "id" => 2942

```

**mapping**

```auto

А чем [Completion Suggester](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-suggesters.html#completion-suggester) не подходит?

</div>

дело в том, что по сути поиск выполняется по title,  
если полностью title туда скормить , то вывод будет полного title и эффет добавления одного слова пропадает.  
пробовал положить в suggester данные  
"title\_tags" : [  
0 =\> "Холодильник"  
1 =\> "Холодильник ATLANT"  
2 =\> "Холодильник ATLANT ХМ"  
3 =\> "Холодильник ATLANT ХМ 4423-060"  
4 =\> "Холодильник ATLANT ХМ 4423-060 N"  
]  
но требуемого эфета не получилось

</div>

так же были попытки с такой структурой:  
{  
"suggest" : [  
{  
"input": "Холодильник",  
"weight" : 5  
},  
{  
"input": "Холодильник ATLANT",  
"weight" : 4  
},  
{  
"input": "Холодильник ATLANT ХМ",  
"weight" : 3  
},  
{  
"input": "Холодильник ATLANT ХМ 4423-060",  
"weight" : 2  
},  
{  
"input": "Холодильник ATLANT ХМ 4423-060 N",  
"weight" : 1  
}  
]  
}  
тоже безрезультатно,

подскажите, какую именно структуру данных выбрать для suggestions?

Я бы как-то так начал:

```auto

DELETE test

PUT test
{
    "mappings": {
        "properties" : {
            "suggest" : {
                "type" : "completion"
            },
            "title" : {
                "type": "keyword"
            }
        }
    }
}

PUT test/_doc/1?refresh
{
    "suggest" : {
        "input": ["Холодильник ATLANT ХМ 4423-060 N"],
        "weight" : 34
    }
}

PUT test/_doc/2?refresh
{
    "suggest" : {
        "input": ["Холодильник INDESIT DS 4160 S"],
        "weight" : 34
    }
}
