使用數組的ElasticSearch bool搜索

Question

我希望能夠排除ElasticSearch查詢中的多個節點。目前這段代碼運行良好，但它只會排除兩個節點（$ nodeId1和$ nodeId2）。

我將如何更改此查詢，以便我可以使用包含儘可能多的節點ID的數組？謝謝。

$data_string = '{ 
    "from" : 0, "size" : "' . $maximumResults . '", 
    "query": { 
     "filtered": { 
      "query": { 
       "match" : { 
        "thread.title" : { 
         "query" : "' . $threadTitle . '", 
         "operator": "or" 
        } 
       } 
      }, 
      "filter": { 
       "bool" : { 
        "must" : [], 
        "must_not" : [ 
         { 
          "term" : {"thread.discussion_id" : "' . $currentThreadId . '"} 
         }, 
         { 
          "term" : {"thread.node" : "' . $nodeId1 . '"} 
         }, 
         { 
          "term" : {"thread.node" : "' . $nodeId2 . '"} 
         }          
        ], 
        "should" : [] 
       } 
      } 
     } 
    } 
}';

您可以使用術語過濾器：

$data_string = '{ 
    "from" : 0, "size" : "' . $maximumResults . '", 
    "query": { 
     "filtered": { 
      "query": { 
       "match" : { 
        "thread.title" : { 
         "query" : "' . $threadTitle . '", 
         "operator": "or" 
        } 
       } 
      }, 
      "filter": { 
       "bool" : { 
        "must" : [], 
        "must_not" : [ 
         { 
          "term" : {"thread.discussion_id" : "' . $currentThreadId . '"} 
         }, 
         { 
          "terms" : {"thread.node" : ["' . $nodeId1 . '", "' . $nodeId2 . '", "' . $nodeId3 . '"} 
         }          
        ], 
        "should" : [] 
       } 
      } 
     } 
    } 
}';
