Hello. Today I've tried the Fuzzy Lookup addin both in Excel 2016 and Excel 365, and in both cases, very similar strings get a very low similarity (0.001) and with a slightly smaller change they don't get matched at all.
Steps to reproduce:
Open the example file from the addin folder (Portfolio.xlsx)
Click the Fuzzy Lookup icon to open the dialog
Select the Portfolio and SP500_data tables
Choose "Company" in both left and right tables
Leave all defaults and click Go to create the comparison table
Expected result: different similarity values as high as 90% (as seen in this article, with the same data).
Result I get: all matches have 0.001 similarity.
Exactly the same has happened with other data I have written as tests. I haven't found any parameter that lets me get different results.
Do you have any idea why this could be happening? Thanks!
