    Methods in org.apache.lucene.search.similarities with parameters of type FieldInvertState
    Modifier and Type | Method and Description
    --- | ---
    `long` | TFIDFSimilarity.`computeNorm(FieldInvertState state)`
    `long` | SimilarityBase.`computeNorm(FieldInvertState state)` Encodes the document length in the same way as `TFIDFSimilarity`.
    `abstract long` | Similarity.`computeNorm(FieldInvertState state)` Computes the normalization value for a field, given the accumulated state of term processing for this field (see `FieldInvertState`).
    `long` | PerFieldSimilarityWrapper.`computeNorm(FieldInvertState state)`
    `long` | MultiSimilarity.`computeNorm(FieldInvertState state)`
    `long` | BM25Similarity.`computeNorm(FieldInvertState state)`
    `abstract float` | TFIDFSimilarity.`lengthNorm(FieldInvertState state)` Compute an index-time normalization value for this field instance.
    `float` | DefaultSimilarity.`lengthNorm(FieldInvertState state)` Implemented as `state.getBoost()*lengthNorm(numTerms)`, where `numTerms` is `getLength()` if `DefaultSimilarity.setDiscountOverlaps(boolean)` is false, else it's `getLength()` - `getNumOverlap()`.
