我想通過搜索只顯示Elasticsearch中的一條記錄

Question

使用以下查詢：

GET feeds/_search
{
  "query": {
    "nested": {
      "path": "comment",
      "query": {
        "multi_match": {
          "query": "ali",
          "fields": ["body","title","comment.c_text"]
        }
      }
    }
  }
}

我得到了結果

{
  "took" : 1,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 1,
      "relation" : "eq"
    },
    "max_score" : 0.8025915,
    "hits" : [
      {
        "_index" : "feeds",
        "_type" : "_doc",
        "_id" : "NeoTNIUB1Qg_7rFp-8RV",
        "_score" : 0.8025915,
        "_source" : {
          "feed_id" : "1",
          "title" : "Mateen",
          "body" : "This is mateen",
          "comment" : [
            {
              "c_id" : "11",
              "feed_id" : "1",
              "c_text" : "get well soon mateen"
            },
            {
              "c_id" : "12",
              "feed_id" : "1",
              "c_text" : " Ali here"
            }
          ]
        }
      }
    ]
  }
}

我不想看到我的第一條記錄，因為它在正文、標題、評論文本中不包含“ali”。 誰能幫忙？ 我希望如果它正在搜索“ali”，那么它將返回 feed id title body 以及評論 id feed id 和 c_text 但不要向我顯示不包含 ali 的數組內容隱藏它

{
  "c_id" : "11",
  "feed_id" : "1",
  "c_text" : "get well soon mateen"
}

我不想在我的輸出中看到這個內容

首先，像這樣更新您的映射：

POST feeds/_mapping
{
  "properties": {
    "title": {
      "type": "text",
      "analyzer": "lowercase"
    },
    "body": {
      "type": "text",
      "analyzer": "lowercase"
    },
    "comment": {
      "type": "nested",
      "properties": {
        "c_text": {
          "type": "text",
          "analyzer": "lowercase"
        }
      }
    }
  }
}

然后運行這個查詢

{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "title": {
              "query": "ali",
              "analyzer": "lowercase"
            }
          }
        },
        {
          "match": {
            "body": {
              "query": "ali",
              "analyzer": "lowercase"
            }
          }
        },
        {
          "nested": {
            "path": "comment",
            "query": {
              "match": {
                "comment.c_text": {
                  "query": "ali",
                  "analyzer": "lowercase"
                }
              }
            }
          }
        }
      ]
    }
  }
}

    GET feeds/_search
{
  "query": {
    "bool": {
      "should": [
        {
          "nested": {
            "path": "comment",
            "query": { 
              "match": {
                "comment.c_text": "hey"
              }
            },"inner_hits": {
              "highlight": {
                "require_field_match": "true"
                
              }
            }
          }
        },
        {
          "term": {
            "title": {
              "value": "hey"
            }
          }
        },
        {
          "term": {
            "body": {
              "value": "hey"
            }
          }
        }
      ]
    }
  }
}

這樣我們就可以通過內部命中得到結果
