如何執行elasticsearch

Question

一個多層次的邏輯查詢比方說，我們有這樣的查詢

（A或B或C）和（X或Y或Z）和（F或G或H）。 ..

我們如何使用Elasticsearch執行此類查詢？ 我試過布爾查詢，但我仍然感到困惑必須的，應該......條款以及如何放置不同的條件，這些條款以獲得合理的結果

這裏是我的數據（場型）樣本：

我需要的到底是篩選課程是這樣的：

（組別或類別2 ...）和（格式或FORMAT2 ...）和 （LANGUAGE1或LANGUAGE2）...

Answer 1

您可以使用bool queries與terms query結合所期望的行爲

GET _search 
{ 
    "query" : { 
     "bool": { 
     "must": [ //AND 
      { 
      "terms": { 
       "category.name": [ // Category with value VALUE1 or VALUE2 
       "VALUE1", 
       "VALUE2" 
       ] 
      } 
      }, 
      { 
      "terms": { 
       "format": [// format with value FORMAT1 or FORMAT2 
       "FORMAT1", 
       "FORMAT2" 
       ] 
      } 
      }, 
      { 
      "terms": { 
       "language": [// language with value LANG1 or LANG2 
       "LANG1", 
       "LANG2" 
       ] 
      } 
      } 
     ] 
     } 

    } 
} 

此外，請確保該用於term匹配的領域，都not_analyzed。 請從這裏開始閱讀映像：http://www.elasticsearch.org/guide/reference/mapping/。

Answer 2

Elasticsearch Query String Query的功能與您正在尋找的功能相同。

請看下面的代碼片段從官方的文檔here

GET /_search 
{ 
    "query": { 
     "query_string": { 
      "query": "(content:this OR name:this) AND (content:that OR name:that)" 
     } 
    } 
} 

希望這有助於提取！
