Hi @DultonM and @MarqueeCrew,
Haha, right, I tested and found a video related to using fuzzy match.
The matchscore_data is supposed to be the score for threshold defined in match function of each matching fields.
So that's correct when you defined four fields with match functions available (i.e. not match key only), then you have 4 scores + 1 overall score.
That's very useful. Thanks!!!
