Which types of documents are automatically excluded from an analytics index search by Relativity?

The correct choice is documents larger than 30 MB. In Relativity, the system has predefined limitations regarding the size of documents that can be indexed for analytics searches. Specifically, any documents exceeding this size threshold are automatically excluded from the index to maintain efficient processing and performance during searches.

This exclusion is important because larger documents can significantly increase the processing time, resource consumption, and complexity of indexing. Therefore, keeping the analytics index manageable is crucial for ensuring optimal performance during searches and analyses.

Other options mention different size thresholds or categories of documents, like attachments or confidential documents. However, they do not align with the Specifically defined size limitation instituted by Relativity for analytics indexing. This ensures that users are provided with relevant and efficiently processed data during their searches.
