Select the match algorithms you want to use from the Matching Function column and the null operator from the
Handle Null column.
In this example two match keys are defined, you want to use the Levenshtein and Jaro-Winkler match methods on first names and last names
respectively and get the duplicate records.
If you want to use an external user-defined matching algorithm, select
Custom and use the Custom Matcher column to load the Jar file of the user-defined
algorithm.
For further information about the
match rule algorithms and parameters, see the tMatchGroup documentation in the Talend Components Reference
Guide.
