Why the difference?
Semantic search converts your query into a vector embedding and finds concepts with similar meaning using cosine similarity. It understands that "irrational choices" relates to "cognitive bias" even without matching keywords.
Keyword search only finds exact text matches. If your words don't appear in the content, you won't find it—even if it's exactly what you're looking for.
