我在单个实例中使用solr 5.5版本。我试图将以下数据索引为一条记录：

我收到未知命令MLID错误：

你能帮我创建索引吗？

谢谢， Srilu

Answer 1

简短回答：把[]放在整个结构周围，它应该可以工作。

答案很长：Solr接受3 different forms中的JSON：

单个任意JSON文档，Solr智能映射到内部字段，根据需要（使用无模式）方法创建它们。请求处理程序是* / update / json / docs“这有效，但不支持子项，也将所有新字段映射到multiValued类型。
单个任意JSON文档，Solr期望它是一系列命令，例如添加，删除和提交。这是Solr特定格式，并且支持子文档。对此的请求是“/ update”
上面的一个多文档快捷方式，其中只有文档以数组形式提供，包括子支持。

你在这里遇到了用例2，所以Solr抱怨说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，切换到类型3，它应该工作。

P.S。您的具体示例似乎有其他嵌套对象数组，可能会停止索引（特别是“辅助”）。但这是一个单独的问题/问题。
