dtSearch text extraction does not populate which of the following properties?

The correct answer is that dtSearch text extraction does not populate properties related to Track Changes, Hidden Data, and Speaker Notes in Word, Excel, and PowerPoint documents. This is because dtSearch primarily focuses on indexing and searching text content rather than extracting specific metadata or non-visible content, which includes revisions, annotations, and speaker notes.

Track Changes in Word or Excel is a feature that records edits made to a document, while Hidden Data in Word or PowerPoint consists of elements like comments, and formatting marks that are not displayed in the main content area. Speaker Notes in PowerPoint are intended for the presenter and provide additional context that is not visible to the audience during a presentation.

Since dtSearch is designed mainly for textual searches and does not delve into these specialized data categories, it effectively leaves out these properties when performing text extraction. Therefore, the answer reflects that all listed properties are not populated by dtSearch text extraction.
