Usage

from sentence_transformers import SentenceTransformer
import numpy as np

model = SentenceTransformer("LoveJesus/biblical-topical-search-chirho")

query = "What does the Bible say about forgiveness?"
verses = [
    "For if ye forgive men their trespasses, your heavenly Father will also forgive you. - Matthew 6:14",
    "In the beginning God created the heaven and the earth. - Genesis 1:1",
    "As far as the east is from the west, so far hath he removed our transgressions from us. - Psalm 103:12",
]

query_emb = model.encode([query])
verse_embs = model.encode(verses)

scores = np.dot(verse_embs, query_emb.T).flatten()
ranked = sorted(zip(scores, verses), reverse=True)
for score, verse in ranked:
    print(f"  {score:.3f}: {verse}")
