Which of the following is a requirement for creating a Saved Search for an Active Learning project?

To create a Saved Search for an Active Learning project, it is essential that the search be public. This requirement is in place because Active Learning is a collaborative process that relies on multiple users across the organization being able to access and contribute to the project. A public Saved Search ensures that all team members involved in the Active Learning project can see the same set of documents, enabling consistent training of the machine learning models used for predictive coding and document review.

The other options are not requirements for creating a Saved Search. While returning extracted text, including families, and suppressing duplicates can enhance the effectiveness of the search results, they are not mandatory criteria for the creation of the Saved Search itself. They may be features that a user can choose to implement based on the specific needs of the project but do not serve as prerequisites for the search to exist within the context of Active Learning.
