ES数据类型

           "ent_name": {
                "type": "text",
                "store": true,
                "index": true,

                    }
                }
            }

模糊查询：

GET ${indexName}/_doc/_search
{
    "query": {
        "query_string":{
            "query":"北京",
            "default_field" : "ent_name"
        }
        
    }
}

精确查询：

GET ${indexName}/_doc/_search
{
    "query": {
        "term": {
            "ent_name.raw": "上海齐鲜餐饮有限公司"
        }
    }
}
