方式一
查询该索引下的所有记录，但只显示 前10条 记录
GET /toutiao_v1/_search
方式二
GET /toutiao_v1/_search
{
"size": 11 //不加size，默认只显示前10条记录
}
方式三
match_all 表示 匹配所有，如下：
GET /toutiao_v1/_search
{
"query": {
"match_all": {} // 内部是空的
},
"size": 100 //不加size，默认只显示前10条记录
}
执行结果如下：
{
"took": 81, // 耗费时间，单位：毫秒
"timed_out": false,

ElasticSearch 条件查询、分页查询、指定查询字段、排序
