如何在Solr中进行部分更新？

根据solr文件

---

原子更新文档的核心功能要求架构中的所有字段都必须配置为存储（stored=“true”）或docValues（docValues=“true”）字段，但在将内容索引到第一个核心后，您是否在任何时候更改了第一个核心的架构？该错误不是由

name

字段引起的，它与包含子文档的文档相关：

//安全检查：不允许更新包含子文档的现有文档，除非我们实际支持此操作。

在Solr 8.8中已删除了产生错误的代码路径，因此升级可能会解决您的问题。但是，请注意，参考指南中的注释与字段本身无关。如果您提交该字段的内容，一切都会很好。但是，如果您只提交其他某个字段的内容，Solr将无法获取

name

字段的实际值，该字段将丢失。@MatsLindh不，我没有更改架构文件，实际上，我在两个核心中都索引了相同的文档，并且我的所有文档都有嵌套文档
