Elasticsearch自動完成 - 從點和空白完成建議匹配輸入

我試圖根據標題(string as "Hunter Game", "Hunter", "HunterGame", "Hunter-Game")和包名稱(string as "az.com.hsz.hunter.game", "az.com.hsz.hunter-game", "az.com.hsz.hunter_game", "az.com.hsz.hunterGame")創建自動完成建議。Elasticsearch自動完成 - 從點和空白完成建議匹配輸入

映射情況如下：

{ 
    "app-search-test": { 
    "mappings": { 
     "package": { 
     "properties": 
     {"title": { 
      "type": "string", 
      "analyzer": "autocomplete" 
      }, 
      "package_name": { 
      "type": "string" 
      }, 
      "title-suggest": { 
      "type": "completion", 
      "analyzer": "simple", 
      "payloads": true, 
      "preserve_separators": false, 
      "preserve_position_increments": true, 
      "max_input_length": 50 
      } 
     } 
     } 
    } 
    } 
}

文檔與建議字符串是：

{ 
    "title": "HUnter Game", 
    "package_name": "az.com.hsz.hunter.game", 
    "title-suggest": { 
       "output": "Hunter Game", 
       "input": "[az.com.hsz.hunter.game, Hunter Game]", 
       "payload": { 
        "package_name": "az.com.hsz.hunter.game", 
        "icon": "<some-url>", 
        "developer": "Vish", 
        "id": "az.com.hsz.hunter.game", 
        "title": "Hunter Game" 
       } 
       } 
}

指標設定：

"analysis": { 
      "filter": { 
      "words_splitter": { 
       "type": "word_delimiter", 
       "preserve_original": "true", 
       "catenate_all": "true" 
      }, 
      "ngram": { 
       "type": "ngram", 
       "min_gram": "2", 
       "max_gram": "15" 
      } 
      }, 
      "analyzer": { 
      "autocomplete": { 
       "type": "custom", 
       "filter": [ 
       "standard", 
       "lowercase", 
       "stop", 
       "kstem", 
       "ngram", 
       "words_splitter" 
       ], 
       "tokenizer": "keyword" 
      } 
      } 
     }

我期望得到的建議獵人遊戲，查詢az.com.hsz.hunter.game或Hunter Game，它可以是標題或包裝nam即但是對於輸入爲"input": "[az.com.hsz.hunter.game, Hunter Game]"的文檔，獲得第一個輸入值az.com.hsz.hunter.game的預期暗示而不是第二個Hunter Game。如果輸入反轉"input": "[Hunter Game, az.com.hsz.hunter.game]"建議Hunter Game，但不是az.com.hsz.hunter.game。

它是如何工作的？

我想不出你是在製作輸入整個字符串而不是字符串列表。

"input": ["az.com.hsz.hunter.game", "Hunter Game"]

將工作。

當前"[az.com.hsz.hunter.game, Hunter Game]"被認爲是一個字符串，因此您根據任何第一個字符得到結果。
