FAQ

Questions BM25 Scorer owners ask.

  • 01

    How does the scoring work?

    The engine uses the BM25 algorithm, calculating IDF based on corpus size and term prevalence, then applying length normalization and saturation constants.

  • 02

    Do I need an LLM to calculate scores?

    No, this capability provides deterministic mathematical results using the compute_relevance_score function without any LLM involvement.

  • 03

    What inputs are required for scoring?

    You must provide query tokens, document tokens, corpus size, term document counts, and average document length.
