具有嵌套对象的Solr模式

Question

我在单个实例中使用solr 5.5版本。 我正在尝试将以下数据索引为一条记录：

我收到未知命令MLID错误：

您能帮我建立索引吗？

谢谢，斯里露

Answer 1

简短的答案：将[]放在整个结构周围，它应该起作用。

长答案：Solr接受3种不同形式的 JSON：

1. Solr可以智能地映射到内部字段的单个任意JSON文档，并根据需要（使用无模式）创建它们。 该请求的处理程序为* / update / json / docs“。这有效，但不支持子级，并且还将所有新字段映射为multiValued类型。
2. Solr期望它是一个命令序列，例如add ， delete和commit的单个任意JSON文档。 这是Solr特定的格式，并且确实支持子文档。 该请求是“ / update”
3. 上面一个文档的多文档快捷方式，其中仅以阵列形式提供文档，包括子支持。

您在此处遇到用例2，因此Solr抱怨它看到的第一件事不是已知命令之一。 通过将对象放入数组，可以切换到类型3，它应该可以工作。

Ps您的特定示例似乎还有其他嵌套对象数组，这些数组可能会停止索引编制（特别是“子公司”）。 但这是一个单独的问题。
