Maximum number of matches to output per lookup
Specify the maximum number of matches the transformation can return for each input row. The default is 1.
Set the similarity threshold at the component level by using the slider. The closer the value is to 1, the closer the resemblance of the lookup value to the source value must be to qualify as a match. Increasing the threshold can improve the speed of matching since fewer candidate records need to be considered.
Specify the delimiters that the transformation uses to tokenize column values.
