Which field is typically used when setting up a saved search for an analytics index?

When setting up a saved search for an analytics index, the Extracted Text field is pivotal because it contains the content and metadata extracted from documents. This field is specially designed to facilitate searches across large datasets by allowing users to retrieve text-based information efficiently.

The Extracted Text field enables users to perform in-depth text analysis, which is often a key component of analytics. When creating a saved search, it is important to leverage this field to ensure that the search captures relevant content based on the text extracted from documents. This capability is particularly useful when trying to analyze trends, keywords, or other textual data.

In contrast, the Document ID field, Title field, and Author field may serve other functions in the management and retrieval of documents, but they do not provide the same depth of content utility as the Extracted Text field when it comes to analytics. The Document ID field is primarily used for identifying documents uniquely, while the Title and Author fields provide specific metadata about the documents. However, they do not encompass the comprehensive text data that the Extracted Text field does, which is essential for effective analytics-based searches.
