Common Mistakes to Avoid

⚠️

Punctuation attached to words

Solution: "word," and "word" are different. Remove punctuation first for accurate filtering.

⚠️

Case variations missed

Solution: Filtering "Error" won't catch "error". Normalize case first or use case-insensitive matching.

⚠️

Word order lost

Solution: Filtering keeps/removes words but may change positions. May affect sentence meaning.
