前言
在使用ElasticSearch构建检索条件，以及解析命中记录的过程中，发现命中商品的记录数和实际页面的展示不符合
正常情况下是一排展示四个商品数据，我现在是命中的商品记录数是20多个，但是是一页只展示了一个数据。
1、问题排查过程
当时并不清楚ElasticSearch 的具体使用，迫不得已转头回去学这个。
1.1 查看构建检索条件
在控制台上打印出构建的检索条件
格式化检索条件

查看命中的记录数
1.3 Debug模式
在对检索出来的数据进行处理的时候，放入商品信息列表的数据的确是一个。
2、问题解决
2.1 问题分析
我还是通过查看构建的检索条件中得知，这里的size是每页展示多少个数据。那我就在构建检索条件的时候放大这个每页展示的条数
2.2 实际效果
每页展示四条数据
每页展示16条数据
