爲什麼elasticsearch建議者返回多個相等的對象？

Question

我正在和建議者一起玩，想知道爲什麼結果集總是有多個相同的對象。

實施例請求：

{"suggest": { 
    "test" : { 
     "text": "holz", 
     "term" : { 
      "field":"title" 
     } 
    } 
}} 

結果：

{"suggest": { 
    "test": [ 
    { 
     "text": "holz", 
     "offset": 0, 
     "length": 4, 
     "options": [...] 
    }, 
    { 
     "text": "holz", 
     "offset": 0, 
     "length": 4, 
     "options": [...] 
    }, 
    { 
     "text": "holz", 
     "offset": 0, 
     "length": 4, 
     "options": [...] 
    }, 
    { 
     "text": "holz", 
     "offset": 0, 
     "length": 4, 
     "options": [...] 
    } 
    ] 
}} 

即使在options對象是完全一樣的。無論我想要什麼樣的文字，它總是一樣的。這有什麼解釋嗎？

ES版本是2.3.4

您是否嘗試過向您的文檔添加有效載荷？

https://www.elastic.co/guide/en/elasticsearch/reference/2.1/search-suggesters-completion.html

curl -X PUT 'localhost:9200/music/song/1?refresh=true' -d '{ 
"name" : "Nevermind", 
"suggest" : { 
    "input": [ "Nevermind", "Nirvana" ], 
    "output": "Nirvana - Nevermind", 
    **"payload" : { "artistId" : 2321 },** 
    "weight" : 34 
}
