Я пытаюсь реализовать частичное совпадение с использованием ngrams в elasticsearch, но не получая ожидаемых результатов от него.
Я по этой ссылке: -Результаты поиска elasticsearch ngrams ошибочны
https://www.elastic.co/guide/en/elasticsearch/guide/current/_index_time_search_as_you_type.html
Я сделал все вещи, которые упоминаются в этой связи. Мой набор данных содержит 3 поля i.e id, name, age.
Вот мое отображение и настройка my_index
GET /my_index/_settings
{
"my_index": {
"settings": {
"index": {
"creation_date": "1433249154544",

}
}
},
"number_of_shards": "1",
"version": {
"created": "1040499"
}
}
}
}
}
GET /my_index/_mapping/my_type
{
"my_index": {
"mappings": {
"my_type": {
"properties": {
"@timestamp": {
"type": "date",
"format": "dateOptionalTime"
},
"@version": {
"type": "string"
},
"age": {

},
"host": {

},
"id": {

},
"message": {

},
"name": {

"index_analyzer": "autocomplete",
"search_analyzer": "standard"
},
"path": {
"type": "string"
},
"type": {
"type": "string"
}
}
}
}
}
}
Мой запрос упругим поиска является: -
GET /my_index/my_type/_search
{
"query": {
"match": {
"name": {
"query": "raman r"
}
}
}
}
По мне н вл результаты должны отображаться только «комбинационный баран», но он также показывает другие результаты, а также: -
