fuzzy match duplicating records

8 - Asteroid

Could someone explain to me why Fuzzy Match is showing me duplicate pairings of Record IDs using the merge option? Record IDs are unique between source id fields. I can de-dupe easily but I don't understand why it's doing this.

Hi @bb213 ,


The Merge mode compares records from different sources, with the intent to identify duplicates across different input files. The trick is to add a unique tool afterwards for RecordID & RecordID2, that way it is not matching twice from each column.

The fuzzy matching videos on this page are a good resource: https://community.alteryx.com/t5/Videos/Live-Training-Index-amp-Welcome/m-p/45161/thread-id/41


The beginner video mentions duplicates in the output of the fuzzy match tool.  I think this happens when you have the option checked for Generate Keys for Each Word.

Training videos say to ALWAYS put that unique filter following the Fuzzy logic tool...
