elasticsearch通配符搜索和運算符

Question

我正在開發一個使用彈性搜索的應用程序，並且在某些情況下，我想根據術語和語言環境進行搜索。我在本地主機上

http://localhost:9200/index/type/_search 

測試這個和參數

query : { 
         wildcard : { "term" : "myterm*" } 
        }, 
        filter : { 
         and : [ 
          { 
           term : { "lang" : "en" } 
          }, 
          { 
           term : { "translations.lang" : "tr" } //this is subdocument search 
          }, 
         ] 
        } 

下面是一個例子文件：

{ 
    "_index": "twitter", 
    "_type": "tweet", 
    "_id": "5084151d2c6e5d5b11000008", 
    "_score": null, 
    "_source": { 
     "lang": "en", 
     "term": "photograph", 
     "translations": [ 
     { 
      "_id": "5084151d2c6e5d5b11000009", 
      "lang": "tr", 
      "translation": "fotoğraf", 
      "score": "0", 
      "createDate": "2012-10-21T15:30:37.994Z", 
      "author": "anonymous" 
     }, 
     { 
      "_id": "50850346532b865c2000000a", 
      "lang": "tr", 
      "translation": "resim", 
      "score": "0", 
      "createDate": "2012-10-22T08:26:46.670Z", 
      "author": "anonymous" 
     } 
     ], 
     "author": "anonymous", 
     "createDate": "2012-10-21T15:30:37.994Z" 
    } 
    } 

我試圖獲得與輸入語言使用通配符條款（自動完成） 「en」，輸出語言「tr」。它正在獲得具有「myterm」的條款，但不適用於此操作。任何建議將事先

Answer 1

我已經設法解決我的問題，以下查詢;

query : { 
    wildcard : { "term" : "myterm*" } 
}, 
filter : { 
    and : [ 
     { 
     term : { "lang" : "en" } 
     }, 
     { 
     term : { "translations.lang" : "tr" } //this is subdocument search 
     } 
    ] 
}, 
sort : { 
    {"term" : "desc"} 
} 

這裏重要的一點是，您需要將排序字段設置爲not_analyzed。因爲，你不能排序分析的字段。

我猜想，translations元素具有nested型理解

感謝。如果是這樣，你應該使用nested查詢：

curl -XPOST "http://localhost:9200/twitter/tweet/_search" -d '{ 
    query: { 
     wildcard: { 
      "term": "term*" 
     } 
    }, 
    filter: { 
     and: [{ 
      term: { 
       "lang": "en" 
      } 
     }, { 
      "nested": { 
       "path": "translations", 
       "query": { 
        "term" : { "translations.lang" : "tr" } 
       } 
      } 
     }] 
    } 
}'
