Abstract: A search engine may maintain a list of derived metadata. When an event occurs that requires updating a search index, the search engine can determine which metadata is derived metadata and take appropriate actions with respect to the derived metadata. For example, if a request is received to update the index for a particular object, the search engine may protect the derived metadata from change while updating the other metadata in the index. As another example, if a request is received to update the text content for the object, the search engine may change the text content and the derived metadata. By identifying derived metadata, the search engine can protect the derived metadata from change when a request is received that otherwise causes metadata to change and can change the derived metadata when a request is received that would otherwise not change the metadata portion of the index.

Abstract translation: 搜索引擎可以维护派生元数据的列表。 当发生需要更新搜索索引的事件时，搜索引擎可以确定哪些元数据是衍生的元数据，并针对导出的元数据采取适当的操作。 例如，如果接收到用于更新特定对象的索引的请求，则搜索引擎可以在更新索引中的其他元数据的同时保护所导出的元数据的变化。 作为另一示例，如果接收到用于更新对象的文本内容的请求，则搜索引擎可以改变文本内容和导出的元数据。 通过识别导出的元数据，当接收到请求时，搜索引擎可以保护导出的元数据，否则导致元数据改变，并且当接收到否则不会改变索引的元数据部分的请求时，可以更改导出的元数据。
