谷粒商城学习——P115 es进阶-bool复合查询

本文主要是介绍谷粒商城学习——P115 es进阶-bool复合查询，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

bool用来做复合查询

复合语句可以合并，任何其他查询语句，包括符合语句。这也就意味着，复合语句之间可以互相嵌套

　　must：必须所有条件，会贡献相关性得分
　　must_not：必须满足所有条件，不会贡献相关性得分
　　should：应该满足should所列举的条件。满足条件最好，不满足也可以，满足得分更高

GET bank/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "gender": "M"
          }
        },
        {
          "match": {
            "address": "mill"
          }
        }
      ],
      "must_not": [
        {
          "match": {
            "age": "18"
          }
        }
      ],
      "should": [
        {
          "match": {
            "lastname": "Wallace"
          }
        }
      ]
    }
  }
}

返回结果
