Scoring Theory

  • source:

  • scoring composed of

    • Fuzziness score
    • Key weight
    • Field-length norm
  • Whether the score should be included in the result set.

    • A score of 0indicates a perfect match, while a score of 1 indicates a complete mismatch.
  • The fuzziness score is internally calculated via a modified implementation of the Bitap algorithm.

  • key weight:

    • User inputted weight of the key. The higher the weight, the higher its relevance score. This is optional, athough Fuse.js will internally default it to 1 if one isn't provided. This boosting is applied at query time.
