Fuzzy Match - Key Match only - Not working as expected

Hi there,

 

I am fuzzy matching two data sources with city and country information. Source one having clean information and source two four columns with a lot of other garbage in it.

In a first step I indentified the country information out of four different columns of source two.

In a second step I want to fuzzy match the city information out of the very same four columns from source two but leverage the country information of the first step.

Therefore I setup the fuzzy match tool to conduct firstly a "Key Match Only" (Generate Keys: "Whole Filed (Case Insensitive)" and Match Function: "None - Key Match Only")

and secondly a fuzzy match on the city name.

 

My expectation was that fuzzy matches on the city name are only conducted if the country name is perfectly the same.

To my surprise this was only true for most of the cases but not ALL the cases.

How is that possible?

 

Cheers Tom

 

P.S. I tried to re create this in a simple example flow, but there everything works as expected Smiley Sad
