Subject [jira] Commented: (LUCENE-446) FunctionQuery - score based on field value
Date Wed, 05 Oct 2005 23:50:53 GMT
    [ ] 

Yonik Seeley commented on LUCENE-446:

Perhaps not  a bad idea considering that the number of classes may top 12 after adding a few
more function types.

Anyone else have package name suggestions/preferences?

> FunctionQuery can return a score based on a field's value or on it's ordinal value.
> FunctionFactory subclasses define the details of the function.  There is currently a
LinearFloatFunction (a line specified by slope and intercept).
> Field values are typically obtained from FieldValueSourceFactory.  Implementations include
FloatFieldSource, IntFieldSource, and OrdFieldSource.
