You can use the all-undecided-review option with the Best clustering method. If a search returns undecided match records, the Best clustering method creates a cluster for the search record. The all-undecided-review option flags the cluster created for the search record and all the existing clusters of the undecided match records. Use Informatica Data Director to manually review the details of all the flagged clusters. You can merge some or all of the clusters or retain them in separate clusters.

For example, you have records with names, Emma Frost in cluster 1 and Em Feast in cluster 2. Add a record with E. Frost as the name to the source table.

During synchronization, the records of Emma Frost and Em Feast match the record of E. Frost with undecided decision. The Best method creates cluster 3 for the record of E. Frost. The all-undecided-review option flags clusters 1, 2, and 3. Use Informatica Data Director to manually review the details of clusters 1, 2, and 3.
