Struct NumericBucketedSimilarity 

pub struct NumericBucketedSimilarity;

Similarity for numeric fields based on relative difference, bucketed into four bands.

Extracts f64 values from Text (parsed), Int, or Float field values and computes relative_diff = |a - b| / max(|a|, |b|, 1.0): relative_diff == 0.0 : 1.0 (exact) relative_diff <= 0.05 : 0.85 (<= 5% difference) relative_diff <= 0.20 : 0.6 (<= 20% difference) relative_diff <= 0.50 : 0.3 (<= 50% difference) otherwise : 0.0
