SQL 类查询的弹性查询

Elastic Query for SQL like query

想在弹性搜索中搜索，就像我们在 SQL query = (age = 25 and name = xyz).

这适用于单个字段和单个数据。

是的，很有可能，就用下面的ES Mapping查询一下：

映射

{
    "mappings": {
        "properties": {
            "name": {
                "type": "text"
            },
            "age" :{
                "type" : "integer"
            }
        }
    },
    "settings": {
        "index": {
            "number_of_shards": "1",
            "number_of_replicas": "1"
        }
    }
}

索引文档

{
    "name": "xyz",
    "age" : 25
}

查询

{
    "query": {
        "bool": {
            "must": [
                {
                    "match": {
                        "name": "xyz"
                    }
                },
                {
                    "match": {
                        "age": 25
                    }
                }
            ]
        }
    }
}

除了接受的答案

POST _sql?format=txt {
"query":"SELECT age, name FROM collection WHERE age=25 AND name ='xyz'"
}
