Class Summary

Class	Description
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
ConstNumberSource	ConstNumberSource is the base class for all constant numbers
ConstValueSource	ConstValueSource returns a constant for all documents
DivFloatFunction	Function to divide "a" by "b"
DocValues	Represents field values as different types.
DoubleConstValueSource
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.
FileFloatSource.ReloadCacheRequestHandler
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.
LiteralValueSource	Pass a the field value through as a String, no matter the type
LongFieldSource	Obtains float field values from the FieldCache using getFloats() and makes those values available as other numeric types, casting as needed.
MaxFloatFunction	MaxFloatFunction returns the max of it's components.
MinFloatFunction	MinFloatFunction returns the min of it's components.
MultiFloatFunction
MultiValueSource	A ValueSource that abstractly represents ValueSources for poly fields, and other things.
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
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.
ValueSourceScorer
VectorValueSource	Converts individual ValueSource instances to leverage the DocValues *Val functions that work with multiple values, i.e.
