Non-Equal Matching and Segment Matching are mutually exclusive. If one is selected, then the other cannot be selected.
Use
non-equal matching
in match rules to prevent equal values in a column from matching each other. Non-equal matching applies only to exact-match columns.
For example, you can use non-equal matching to match a record with a fuzzy organization name column and an exact, non-equal organization type column. Even though organization names are identical, the records will match only if the organization types are not identical.
