---|---|
BoolFunction | |
ByteFieldSource | Obtains int field values from the FieldCache
using getInts()
and makes those values available as other numeric types, casting as needed. |
BytesRefFieldSource | An implementation for retrieving FunctionValues instances for string based fields. |
ConstNumberSource | ConstNumberSource is the base class for all constant numbers |
ConstValueSource | ConstValueSource returns a constant for all documents |
DefFunction | |
DivFloatFunction | Function to divide "a" by "b" |
DocFreqValueSource | DocFreqValueSource returns the number of documents containing the term. |
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 . |
FloatFieldSource | Obtains float field values from the FieldCache
using getFloats()
and makes those values available as other numeric types, casting as needed. |
IDFValueSource | |
IfFunction | |
IntFieldSource | Obtains int field values from the FieldCache
using getInts()
and makes those values available as other numeric types, casting as needed. |
JoinDocFreqValueSource | Use a field value and find the Document Frequency within another field. |
LinearFloatFunction | LinearFloatFunction implements a linear function over
another ValueSource . |
LiteralValueSource | Pass a the field value through as a String, no matter the type // Q: doesn't this mean it's a "string"? |
LongFieldSource | Obtains float field values from the FieldCache
using getFloats()
and makes those values available as other numeric types, casting as needed. |
MaxDocValueSource | |
MaxFloatFunction | MaxFloatFunction returns the max of it's components. |
MinFloatFunction | MinFloatFunction returns the min of it's components. |
MultiBoolFunction | |
MultiFloatFunction | |
MultiFunction | |
MultiValueSource | A ValueSource that abstractly represents ValueSource s for
poly fields, and other things. |
NormValueSource | |
NumDocsValueSource | |
NumericIndexDocValueSource | Expert: obtains numeric field values from a FunctionValues field. |
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 getTermsIndex()
and reverses the order. |
ScaleFloatFunction | Scales values to be between min and max. |
ShortFieldSource | |
SimpleBoolFunction | |
SimpleFloatFunction | A simple float function with a single argument |
SingleFunction | A function with a single argument |
SumFloatFunction | SumFloatFunction returns the sum of it's components. |
SumTotalTermFreqValueSource | TotalTermFreqValueSource returns the total term freq (sum of term freqs across all docuyments). |
TermFreqValueSource | |
TFValueSource | |
TotalTermFreqValueSource | TotalTermFreqValueSource returns the total term freq (sum of term freqs across all docuyments). |
VectorValueSource | Converts individual ValueSource instances to leverage the FunctionValues *Val functions that work with multiple values, i.e. |
A variety of functions to use with FunctionQuery.
