Elasticsearch使用Search After深度分页，分页的方式是上一页的最后一条数据sort里面的值来确定下一页的位置，在分页请求的过程中，有索引数据的增删，会实时的反映到游标上。每一页的数据依赖于上一页最后一条数据，所以不能跳页请求;

使用search_after必须要设置from=0;

最后一条数据里拿到sort属性的值传入到search_after;

curl 第一次请求：

index/type/_search?pretty -d{  "size": 10,  "query": {    "match": {      "age": "男"    }  },  "sort": [{    "_uid": {      "order": "desc"    }  }]}

返回：

{  "took": 28,  "timed_out": false,  "_shards": {    "total": 5,    "successful": 5,    "skipped": 0,    "failed": 0  },  "hits": {    "total": 286,    "max_score": null,    "hits": [{      "_index": "user_member",      "_type": "member_itu",      "_id": "123465",      "_score": null,      "_source": {        "userId": "123456",        "name": "123",        "updateTime": "2022-12-09 13:05"      },      "sort": [        "123465"      ]    }]  }}

curl 分页第二次请求：

index/type/_search?pretty -d{  "size": 10,  "search_after": ["123456"],  "query": {    "match": {      "age": "男"    }  },  "sort": [{    "_uid": {      "order": "desc"    }  }]}

分页返回：

{  "took": 28,  "timed_out": false,  "_shards": {    "total": 5,    "successful": 5,    "skipped": 0,    "failed": 0  },  "hits": {    "total": 286,    "max_score": null,    "hits": [{      "_index": "user_member",      "_type": "member_itu",      "_id": "123457",      "_score": null,      "_source": {        "userId": "123457",        "name": "124",        "updateTime": "2022-12-09 14:05"      },      "sort": [        "123457"      ]    }]  }}
