1.Match多字段查询,同时对多个字段进行查询

    get /index1/_search
    {
      "query":{
        "multi_match": {
          "query": "20",
          "fields": ["name","age"]
        }
      }
    }
    

2.对查询字符串不进行分词，使用term

    et /index1/_search
    {
      "query":{
        "term": {
          "name": {
            "value": "jack"
          }
        }
      }
    }
    

3.批量进行term查询，使用terms

    get /index1/_search
    {
      "query":{
       "terms": {
         "name": [
           "jack",
           "chen",
           "1"
         ]
       }
      }
    }
    

4.使用range对数字或时间进行范围查询

    get /index1/_search
    {
      "query":
      {
        "range": {
          "age": {
            "gte": 10,
            "lte": 20
          }
        }
      }
    }
    

5.不计算相关性得分的查询，会缓存结果，性能高的查询

    get /index1/_search
    {
      "query":
      {
        "bool": {
          "filter": [
            {
              "term": {
                "name": "jack"
              }
            }
          ]
        }
      }
    }
    

6.计算相关性得分，必须满足条件使用must

    GET /index1/_search
    {
      "query": {
        "bool": {
          "must": [
            {
              "match": {
                "name": "jack"
              }
            },
            {
              "match": {
                "age": "10"
              }
            }
          ]
        }
      }
    }
    

7.复合查询使用should时需注意，如果只有should条件，那么至少要满足一个should，如果should和must同时使用，那么should可满足也可不满足，满足会影响加分
