What does the field mapping option "Use for exact duplicate" do?

The option "Use for exact duplicate" serves a critical function in the context of identifying exact duplicates during data processing. When this option is selected, it ensures that the mapped fields are actively considered when determining whether two documents are exact duplicates of each other. This means that only documents that have identical values in the specified fields will be recognized as duplicates.

The significance of this feature lies in its ability to enhance the accuracy of duplicate detection. By including mapped fields in the criteria for duplicates, the system can filter out documents that may be similar but not identical in the relevant aspects, thereby reducing false positives in the duplicate identification process.

In contrast to other options, such as including non-matching fields, creating additional duplicate fields for comparison, or eliminating potential duplicates from the dataset entirely, using mapped fields to check for exact duplicates focuses specifically on matching criteria. This precision is essential for maintaining data integrity and ensuring that only genuinely duplicate documents are flagged for review or potential removal.
