Queries that compute score based upon a function

Classes

BoostedQuery

Query that is boosted by a ValueSource

FunctionQuery

Returns a score for each document based on a ValueSource, often some function of the value of a field.

Note: This API is experimental and may change in non backward-compatible ways in the future

FunctionQuery.AllScorer

FunctionQuery.FunctionWeight

FunctionValues

Represents field values as different types. Normally created via a ValueSource for a particular field and reader.

FunctionValues.ValueFiller

Abstraction of the logic required to fill the value of a specified doc into a reusable Lucene.Net.Util.Mutable.MutableValue. Implementations of FunctionValues are encouraged to define their own implementations of FunctionValues.ValueFiller if their value is not a System.Single.

Note

This API is experimental and might change in incompatible ways in the next release.

ValueSource

Instantiates FunctionValues for a particular reader.

Often used when creating a FunctionQuery.

ValueSourceScorer

Lucene.Net.Search.Scorer which returns the result of SingleVal(Int32) as the score for a document.
