Упругое Поисковое слово

Question

Мы хотим, чтобы упругий поиск подсказывал слова, найденные в индексе.Мы используем версию: 5.6.4.

Если я наберу слово «голова», оно должно предложить «штаб-квартира», слово, найденное в индексе.Желательно сортировать предложения по появлению.

Я пробовал несколько учебных пособий, но все они возвращают весь элемент контента вместо самого слова.Наиболее близким, с чем я столкнулся при использовании документации, является следующее:

GET test_content/_search?pretty
{
  "suggest": { 
      "text": "head", 
      "my-suggestion": { 
         "term": { 
            "field":"autocomplete"
         }
      }
   }
}

Но это не дает результатов, пока я не наберу: "штаб-квартира".

Когда я набираю «лидерство», я ожидаю «лидерство», но в результате получаю «земля».Исправление опечаток может быть хорошим, но не то, что я ищу в данный момент.Сначала я хочу получить стабильную функциональность подсказки рабочего слова и позже включить исправление опечаток.

Я также пытался поиграться с фильтром edgeNGram, но не получил должных результатов.Фильтр whitespace пока должен быть в порядке.Поиск по префиксу меня устраивает.

Конфигурация:

PUT test_content
{
  "settings": {
      "analysis": {
         "analyzer": {
            "whitespace_analyzer": {
               "type": "custom",

               "filter": [
                  "lowercase",
                  "asciifolding"
               ]
            }
         }
      }
   },

    "mydocument": {

              "type": "keyword"
            },
            "completion": {
              "type": "text",
              "analyzer": "whitespace_analyzer",
              "search_analyzer": "standard"
            }
          }
        },
        "title": {
          "type": "text"
        },
        "content": {
          "type": "text"
        }
      }
    }
  }
