根据错误信息,看起来是在执行查询时出现了问题。具体地说,错误信息中提到 `nested object under path [extensions] is not of nested type`,表示在查询中使用了 `nested` 类型,但是 `extensions` 字段并不是一个嵌套类型。
要解决这个问题,你可以按照以下步骤进行操作:
1. 检查索引映射:首先,确认索引 `material_index` 的映射中是否将 `extensions` 字段定义为嵌套类型。你可以通过运行以下命令来查看索引映射:
```
GET material_index/_mapping
```
确保 `extensions` 字段的映射类型为 `nested`。如果不是,你需要更新索引映射以将该字段定义为嵌套类型。
2. 更新索引映射:如果 `extensions` 字段的映射类型不是 `nested`,你需要更新索引映射。可以使用以下命令来更新索引映射:
```json
PUT material_index/_mapping
{
"properties": {
"extensions": {
"type": "nested"
}
}
}
```
这将把 `extensions` 字段定义为嵌套类型。
3. 重新索引数据:一旦索引映射更新完成,你需要重新索引数据,以便新的映射生效。
请注意,在执行上述操作之前,请确保你已经备份了索引数据,并且在生产环境中谨慎操作。如果你对索引映射和嵌套类型不太熟悉,建议参考Elasticsearch的官方文档,或者向Elasticsearch社区和论坛寻求更详细的帮助和指导。
