一、提權，又見boost

GET /forum/article/_search
{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "title": {
              "query": "java spark",
              "boost": 2
            }
          }
        },
        {
          "match": {
            "content": "java spark"
 

          }
        }
      ]
    }
  }
}

二、降分，你不要的也顯出來不過在後面

GET /forum/article/_search 
{
  "query": {
    "boosting": {
      "positive": {
        "match": {
          "content": "java"
        }
      },
      "negative": {
        "match": {
          "content": "spark"
        }
      },
      "negative_boost"
 
: 0.2
    }
  }
}

包含了negative term的doc，分數乘以negative boost，分數降低

三、不需要分數，直接走constant_score加filter，分數都是1

GET /forum/article/_search 
{
  "query": {
    "bool": {
      "should": [
        {
          "constant_score": {
            "query": {
              "match": {
                "title": "java"
              }
            }
          }
        },
        {
          "constant_score"
 
: {
            "query": {
              "match": {
                "title": "spark"
              }
            }
          }
        }
      ]
    }
  }
}

四、重構，用處不大，注意第二個bool

GET /forum/article/_search 
{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "content": "java"
          }
        },
        {
          "match": {
            "content": "spark"
          }
        },
        {
          "bool": {
            "should": [
              {
                "match": {
                  "content": "solution"
                }
              },
              {
                "match": {
                  "content": "beginner"
                }
              }
            ]
          }
        }
      ]
    }
  }
}
