search默认返回总记录数是10000,这将在分页获取最大分页数时不正常显示。
解决方案：
第一步：查询语句设置track_total_hits = true

{
    "query":{
        "match_all":{}
    },
    "track_total_hits":true
}

SearchSourceBuilder searchBuilder = new SearchSourceBuilder();
searchBuilder.trackTotalHits(true);

第二步：修改index的setting设置

http://??/index_name/_settings  
HttpMethod: PUT
HttpBody： 
{ "index" : { "max_result_window" : 100000000}}
