Class Summary

BoostedQuery	Query that is boosted by a ValueSource
ByteFieldSource	Obtains int field values from the FieldCache using getInts() and makes those values available as other numeric types, casting as needed.
ConstValueSource	ConstValueSource returns a constant for all documents
DegreeFunction
DivFloatFunction	Function to divide "a" by "b"
DocValues	Represents field values as different types.
DoubleFieldSource	Obtains float field values from the FieldCache using getFloats() and makes those values available as other numeric types, casting as needed.
DualFloatFunction
FieldCacheSource	A base class for ValueSource implementations that retrieve values for a single field from the FieldCache.
FileFloatSource	Obtains float field values from an external file.
FloatFieldSource	Obtains float field values from the FieldCache using getFloats() and makes those values available as other numeric types, casting as needed.
FunctionQuery	Returns a score for each document based on a ValueSource, often some function of the value of a field.
IntFieldSource	Obtains int field values from the FieldCache using getInts() and makes those values available as other numeric types, casting as needed.
LinearFloatFunction	LinearFloatFunction implements a linear function over another ValueSource.
LongFieldSource	Obtains float field values from the FieldCache using getFloats() and makes those values available as other numeric types, casting as needed.
MaxFloatFunction	Returns the max of a ValueSource and a float (which is useful for "bottoming out" another function at 0.0, or some positive number).
MultiFloatFunction
OrdFieldSource	Obtains the ordinal of the field value from the default Lucene FieldCache using getStringIndex().
PowFloatFunction	Function to raise the base "a" to the power "b"
ProductFloatFunction	ProductFloatFunction returns the product of it's components.
QueryValueSource	QueryValueSource returns the relevance score of the query
RadianFunction	Take a ValueSourc and produce convert the number to radians and return that value
RangeMapFloatFunction	LinearFloatFunction implements a linear function over another ValueSource.
ReciprocalFloatFunction	ReciprocalFloatFunction implements a reciprocal function f(x) = a/(mx+b), based on the float value of a field or function as exported by ValueSource.
ReverseOrdFieldSource	Obtains the ordinal of the field value from the default Lucene FieldCache using getStringIndex() and reverses the order.
ScaleFloatFunction	Scales values to be between min and max.
ShortFieldSource
SimpleFloatFunction	A simple float function with a single argument
SingleFunction	A function with a single argument
StringIndexDocValues	Internal class, subject to change.
SumFloatFunction	SumFloatFunction returns the sum of it's components.
TopValueSource	A value source that wraps another and ensures that the top level reader is used.
ValueSource	Instantiates DocValues for a particular reader.
ValueSourceRangeFilter	RangeFilter over a ValueSource.
