Frequently Asked Questions

Which similarity metric to use?
Jaccard: word overlap only. Cosine: weighted by frequency. Levenshtein: character-level edit distance (catches typos). For RAG chunk dedup: cosine. For near-duplicate detection: Levenshtein ratio.
Is this real embedding similarity?
Non — this is lexical similarity (client-side, no API). For true semantic similarity, you need embedding model. But for many cases (chunk overlap, cache key dedup, approximate match), lexical is fast + good enough.
