针对转载文章https://mp.youkuaiyun.com/mp_blog/creation/editor/118930537中的boost进行验证，发现转载文章中针对boost影响范围说明有误，特进行验证。实际全文索引(match query)、前缀prefix、模糊wildcard、范围查询range都是生效的。

创建索引

PUT /test/
{
  "settings":{
    "index":{
      "number_of_shards" : "3",
      "number_of_replicas" : "0"
    }
  },
  "mappings": {
      "properties":{
        "name":{
          "type":"keyword"
        },
        "age":{
          "type": "long"
        },
        "address":{
          "type":"text"
        }
      }
  }
}

填充数据

POST /test/_doc
{
  "name": "quick",
  "age":10,
  "address":"quick brown one fox five"
}

POST /test/_doc
{
  "name": "quick",
  "age":20,
  "address":"search quick"
}

模糊查询

POST /test/_search
{
  "query": {
    "bool": {
      "should": [
        {
          "wildcard": {
            "address": {
              "value": "*arch",
              "boost" : 2
            }
          }
        },
        {
          "wildcard": {
            "address": {
              "value": "*own",
              "boost" : 3
            }
          }
        }
      ]
    }
  }
}

"hits" : [
      {
        "_index" : "test",
        "_type" : "_doc",
        "_id" : "kCMMzXoBkppsa-8Ho6cl",
        "_score" : 3.0,
        "_source" : {
          "name" : "quick",
          "age" : 10,
          "address" : "quick brown one fox five"
        }
      },
      {
        "_index" : "test",
        "_type" : "_doc",
        "_id" : "kSMMzXoBkppsa-8Hq6dh",
        "_score" : 2.0,
        "_source" : {
          "name" : "quick",
          "age" : 20,
          "address" : "search quick"
        }
      }
    ]

前缀查询

POST /test/_search
{
  "query": {
    "bool": {
      "should": [
        {
          "prefix": {
            "address": {
              "value": "sea",
              "boost" : 2
            }
          }
        },
        {
          "prefix": {
            "address": {
              "value": "br",
              "boost" : 3
            }
          }
        }
      ]
    }
  }
}

"hits" : [
      {
        "_index" : "test",
        "_type" : "_doc",
        "_id" : "kCMMzXoBkppsa-8Ho6cl",
        "_score" : 3.0,
        "_source" : {
          "name" : "quick",
          "age" : 10,
          "address" : "quick brown one fox five"
        }
      },
      {
        "_index" : "test",
        "_type" : "_doc",
        "_id" : "kSMMzXoBkppsa-8Hq6dh",
        "_score" : 2.0,
        "_source" : {
          "name" : "quick",
          "age" : 20,
          "address" : "search quick"
        }
      }
    ]

范围查询

POST /test/_search
{
    "size":30,
    "query":{
        "bool": {
          "should": [

                  "query": "brown",
                  "boost": 5
                }
              }
            },
            {
              "range": {
                "age": {
                  "gte": 15,
                  "lte": 30,
                  "boost": 1
                }
              }
            }
          ]
        }
    }
}

"hits" : [
      {
        "_index" : "test",
        "_type" : "_doc",
