复制步骤：

1. 启动一个新的apache solr干净实例
2. 创建新核心

3. 使用Solr Admin的文档上传工具添加包含以下数据的新文档（在开发模式下，Solr应自动创建字段）。

   { "id": "1", "network_s": "original value" }

4. 然后继续上传新的JSON命令以更新以前上传的文档。

[{"id": "1", "network_s": {"set":"Something else"}}]

我觉得我做错了什么，但是我完全在遵循文档。我正在使用Solr版本8.1.1，并阅读7.7的 latest 文档。

Answer 1

这是Solr 8.1发行版中的错误。降级到7.7可以修复此问题，直到对其进行修补。 https://issues.apache.org/jira/browse/SOLR-13523
