elasticsearch - 增强查询，从文档复制

Question

我正在尝试创建像documentation中所示的提升查询
但是当我尝试

{
  "query": {
    "match_all":{}
  },
  "boosting": {
    "positive": {
      "term": {
        "is_job_seeking": 1
      }
    },
    "negative": {
      "term": {
        "is_job_seeking": 0
      }
    }
  },
  "negative_boost" : 0.2
}

它不起作用，我得到了错误

我也尝试添加 explain: true，但是它没有给我任何有关查询错误的额外信息。

编辑
我已经写过这样的查询

{
  "sort": [
    {
      "is_active": "asc"
    }
  ],
  "fields": [
    "is_job_seeking", "is_active"
  ],
  "query": {
    "bool": {
      "must": [
        {
          "bool": {
            "must": {
              "term": {
                "is_job_seeking": 1
              }
            }
          }
        },
        {
          "boosting": {
            "positive": {
              "term": {
                "is_active": 1
              }
            },
            "negative": {
              "term": {
                "is_active": 0
              }
            },
            "negative_boost": 0.3
          }
        }
      ]
    }
  }
}

这个查询给了我1000个结果，但是没有 is_active=0的文档，当我删除 boosting部分时，我用文档 is_active=0纠正了结果

您的查询应如下所示:

{
  "query": {
    "boosting": {
      "positive": {
        "term": {
          "is_job_seeking": 1
        }
      },
      "negative": {
        "term": {
          "is_job_seeking": 0
        }
      },
      "negative_boost": 0.2
    }
  }
}

用 bool:

{
  "query": {
    "bool": {
      "should": [
        {
          "term": {
            "text": {
              "value": "something"
            }
          }
        },
        {
          "boosting": {
            "positive": {
              "term": {
                "is_job_seeking": 1
              }
            },
            "negative": {
              "term": {
                "is_job_seeking": 0
              }
            },
            "negative_boost": 0.2
          }
        }
      ]
    }
  }
}
