newSaturationQuery
Same as .newSaturationQuery but 1f is used as a weight and a reasonably good default pivot value is computed based on index statistics and is approximately equal to the geometric mean of all values that exist in the index.
Parameters
fieldName
field that stores features
featureName
name of the feature
Throws
if weight is not in (0,64] or pivot is not in (0, +Infinity)
Return a new Query that will score documents as weight * S / (S + pivot) where S is the value of the static feature.
Parameters
fieldName
field that stores features
featureName
name of the feature
weight
weight to give to this feature, must be in (0,64]
pivot
feature value that would give a score contribution equal to weight/2, must be in (0, +Infinity)
Throws
if weight is not in (0,64] or pivot is not in (0, +Infinity)
