### What problem does this PR solve? When I use the categorization operator, I find that if the keyword I want to Categorize appears repeatedly in the input, then I cannot judge the word that appears most frequently. Instead, I simply get the word that matches and return all the ones that have made the following changes to the categorize filter. ### Type of change - [x] Bug Fix (non-breaking change which fixes an issue) - [x] New Feature (non-breaking change which adds functionality) - [x] Refactoring - [x] Performance Improvement
