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：

您能帮我创建索引吗？

谢谢， 斯里鲁

Answer 1

简短的回答：将 [] 放在整个结构周围，它应该可以工作。

长答案：Solr 接受 3 different forms 中的 JSON：

1. Solr 对内部字段进行智能映射的单个任意 JSON 文档，根据需要（使用无模式）方法创建它们。其请求处理程序是 */update/json/docs" 这可行，但不支持子项，并且还将所有新字段映射到多值类型。
2. Solr 期望的单个任意 JSON 文档是一系列命令，例如 add、delete 和 commit。这是特定于 Solr 的格式，并且支持子文档。对此的请求是“/update”
3. 上述多文档快捷方式，其中仅以数组形式提供文档，包括儿童抚养费。

您在这里遇到了用例 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中，您切换到类型 3，它应该可以工作。

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