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 |
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). |
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. |
