Elasticsearch：陣列

Question

的交集假設我的文檔都是這樣

{ 
    "salary": { 
     "max": 1572, 
     "min": 682 
    }, 
    "skills": [ 
     "Modula-3", 
     "Max/MSP", 
     "Arduino", 
     "SPARK", 
     "PL/SQL", 
     "Processing", 
     "Go", 
     "Mathematica", 
     "Modula-2", 
     "IDL", 
     "Heron", 
     "Scheme" 
    ], 
    "company": "Merck", 
    "experience": 0, 
    "role": "Airport Security Screener", 
    "cities": [ 
     "Ahmedabad", 
     "Mangaluru", 
     "Malegaon", 
     "Bokaro Steel City", 
     "Vadodara", 
     "Kollam" 
    ] 
} 

我想要做一個查詢中，我將提供一組城市，並會得到根據路口的基數排序的文件。即假設我的城市集合是["Ahmedabad", "Mangaluru"]，那麼這個查詢與上述文檔的交集的cardinatlity是2.我應該怎麼查詢？

樣品響應

{"_score": 4.0202227, "cities": ["Ahmedabad","Mangaluru","Visakhapatnam", "Vijayawada"]} 
{"_score": 2.27, "cities": ["Ahmedabad","Visakhapatnam", "Vijayawada"]} 
{"_score": 1.79, "cities": ["Mangalauru","Vijayawada", "delhi", "bombay"]} 

我使用elasticsearch 5.2.2

也許這樣的事情會幫助你？

{ 
    "query": { 
    "function_score": { 
     "query": { 
     "match": { 
      "cities": "Ahmedabad Mangaluru" 
     } 
     }, 
     "functions": [ 
     { 
      "filter": { 
      "match": { 
       "cities": "Ahmedabad" 
      } 
      }, 
      "weight": 1 
     }, 
     { 
      "filter": { 
      "match": { 
       "cities": "Mangaluru" 
      } 
      }, 
      "weight": 1 
     } 
     ], 
     "score_mode": "sum" 
    } 
    } 
}
