 Description  « Hide
FunctionQuery can return a score based on a field's value or on it's ordinal value.

FunctionFactory subclasses define the details of the function. There is currently a LinearFloatFunction (a line specified by slope and intercept).

Field values are typically obtained from FieldValueSourceFactory. Implementations include FloatFieldSource, IntFieldSource, and OrdFieldSource.
