ES7.16.2基础操作-评分优化（九）

## 搜索包含java,不包含spark（如果包含spark不会说不需要，而是降低评分）

GET customer/_search
{
  "query": {
    "boosting": {
      "positive": {
        "match": {
          "introduce": "Java"
        }
      },
      "negative": {
        "match": {
          "introduce": "spark"
        }
      },
      "negative_boost": 0.2
    }
  }
}

## 没有评分
GET customer/_search
{
  "query": {
    "bool": {
      "should": [
        {
          "constant_score": {
            "filter": {
              "match": {
                "introduce": "java"
              }
            }
          }
        },
        {
          "constant_score": {
            "filter": {
              "match": {
                "introduce": "spark"
              }
            }
          }
        }
      ]
    }
  }
}
