Hi, I am working on Fuzzy grouping and just stumbled upon Jamie's blog post "Adventures with Fuzzy Grouping". What I am not clear as to how is the join happening towards the end ie based on which columns. How would the data match at the end. for eg: 1 Sudeep 2 Sudeep 3 Sudip In the left branch after 1st sort and removal or dupes we would get: Sudeep Sudip After applying Fuzzy grouping we get : Sudeep Sudeep While on the right side we would get: Sudeep Sudeep Sudip Now how do we join these 2 sets of data to get the original number of rows = 3 and all 3 rows should have sudeep as the value? Please let me know if I am missing something or making a wrong assumption.My Blog | Ask Me
