DSL-关键字查询

# 关键字精确匹配查询 term

term 查询,精确的关键词匹配查询,不对查询条件进行分词。 在 Postman 中,向 ES 服务器发 GET 请求

GET http://localhost:9200/student/_search
1

body

{
    "query": {
        "term": {
            "name": {
            "value": "zhangsan"
            }
        }
    }
}

{

    "timed_out": false,
    "_shards": {
        "total": 1,
        "successful": 1,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": {
            "value": 1,
            "relation": "eq"
        },
        "max_score": 1.540445,
        "hits": [
            {
                "_index": "student",
                "_type": "_doc",
                "_id": "1001",
                "_score": 1.540445,
                "_source": {
                    "name": "zhangsan",
                    "nickname": "zhangsan",
                    "sex": "男",
                    "age": 30
                }
            }
        ]

# 多关键字精确查询 terms

terms 查询和 term 查询一样,可以指定多值进行匹配 如果这个字段包含了指定值中的任何一个值,那么这个文档满足条件,类似于 mysql 的 in 在 Postman 中,向 ES 服务器发 GET 请求

GET http://localhost:9200/student/_search
1

body

{
    "query": {
        "terms": {
            "name": ["zhangsan","lisi"]
        }
    }
}

    "hits": {
        "total": {
            "value": 2,
            "relation": "eq"
        },
        "max_score": 1.0,
        "hits": [
            {

                    "sex": "男",
                    "age": 30
                }
            },
            {
                "_index": "student",
                "_type": "_doc",

                }
            }
