我有一个包含父子关系的弹性搜索实现。 父（产品）类型有两种子类型（productfeatures，supplierpna）。
我的应用程序上有搜索功能，需要根据“产品”类型中的productcode字段返回父文档。
我需要的是将所有附加到父级的子文档作为带有单个过滤查询的子嵌套列表。
e.g。 productcode =“123456”将返回10个产品，但有些产品有子对象，有些没有，但我想得到父文件而不管子文档是否存在。
我尝试了has_child选项，但是当没有子对象时它不会返回父文档
这是我的映射，这方面的任何帮助都会非常有用。

现在，此查询仅返回我希望修改此查询的父文档，以便在每个父文档中包含子对象（productfeatures和supplierpna）。
