Refining the Report: Filters and Exclusions
Use Filters and Exclusions to refine a Similarity Report and focus on the matches that are most relevant to your review.

Use filters to show or hide certain matches and sources according to their relevance. For example, turning on the Bibliography exclusion filter hides matches found in the bibliography or reference list.
