I have a program that uses fuzzywuzzy to match to csvs and find any strings that might be duplicates or very similar. When I compare my two files, fuzzywuzzy raises the following error:
WARNING:root:Applied processor reduces input query to empty string all comparisons will have score 0. [Query:'+']
Anyone have any idea what cause that error to come up?
The error comes from process.extractOne().
Fuzzywuzzy does some cleaning of the queries you give it, including case folding and replacing non-letters and non-numbers with white space.
Your query only contains a plus sign, which is replaced by white space, leaving an empty string, which cannot be fuzzy matched against. That causes the error.
