其他问题

1：要确保运行ES的服务器存储可用空间在10%以上，否则无法创建索引
2: 创建mappings时不能添加多个类型否侧会反馈以下错误：

 "type": "illegal_argument_exception",
                "reason": "Rejecting mapping update to [people2] as the final mapping would have more than 1 type: [woman, man]"

3：重复创建索引会返回以下错误：

{
    "error": {
        "root_cause": [
            {
                "type": "resource_already_exists_exception",
                "reason": "index [people/wooBwVX0T7CFaij7aVUVvw] already exists",
                "index_uuid": "wooBwVX0T7CFaij7aVUVvw",
                "index": "people"
            }
        ],
        "type": "resource_already_exists_exception",
        "reason": "index [people/wooBwVX0T7CFaij7aVUVvw] already exists",
        "index_uuid": "wooBwVX0T7CFaij7aVUVvw",
        "index": "people"
    },
    "status": 400
}

3，设定为keyword类型的属性不能被模糊匹配
4，term与match相比都能模糊匹配，但对于长一点的text内容，term不能匹配，？
