Which search condition when combined with the AND operator produces documents skipped by reviewers during Active Learning?

The condition that combines with the AND operator to produce documents skipped by reviewers during Active Learning is when the AL Designation is Not Set. This condition indicates that there are documents in the dataset that have not yet been assigned a designation, meaning they were not reviewed or categorized by the Active Learning process.

By using this search condition, it highlights documents that are essentially in a neutral state, having not yet been analyzed by reviewers, thus identifying gaps in the review process. This can be crucial for project managers to ensure that all relevant documents are being evaluated and that no pertinent information is overlooked.

Other options may involve reviewers' conditions being set or not set, but they are not directly indicative of whether the documents have been bypassed in the review process. For instance, setting reviewer conditions or marking Active Learning as completed imply a level of review or designation, which does not align with the core issue of identifying documents that were skipped.
