Common Mistakes to Avoid

⚠️

Case sensitivity issues

Solution: "Hello" and "hello" may be treated as different words. Enable case-insensitive for true deduplication.

⚠️

Removing intentional repetition

Solution: Literary repetition ("very very important") may be intentional. Review before bulk removal.

⚠️

Punctuation affecting matches

Solution: "word" and "word," may be seen as different. Consider removing punctuation first for accurate deduplication.
