Method CustomScore

CustomScore(Int32, Single, Single[])

Compute a custom score by the subQuery score and a number of FunctionQuery scores.

Subclasses can override this method to modify the custom score.

If your custom scoring is different than the default herein you should override at least one of the two CustomScore(Int32, Single, Single) methods. If the number of FunctionQuerys is always < 2 it is sufficient to override the other CustomScore(Int32, Single, Single) method, which is simpler.

The default computation herein is a multiplication of given scores:

    ModifiedScore = valSrcScore * valSrcScores[0] * valSrcScores[1] * ...
Declaration
public virtual float CustomScore(int doc, float subQueryScore, float[] valSrcScores)
Parameters
Type Name Description
System.Int32 doc

id of scored doc.

System.Single subQueryScore

score of that doc by the subQuery.

System.Single[] valSrcScores

scores of that doc by the FunctionQuery.

Returns
Type Description
System.Single

custom score.
