类 ScoreFunction

java.lang.Object

com.alicloud.openservices.tablestore.model.search.query.ScoreFunction

public class ScoreFunction
extends Object

Each ScoreFunction is a scoring function, and currently, up to three ScoreFunctions can be used simultaneously for scoring.

Each ScoreFunction includes three types of functions: FieldValueFactorFunction, DecayFunction, and RandomFunction. Please select one of these to configure or leave all unset (use only filter and weight).

The ScoreFunction can set weight and filter, controlling the weight of the scoring (the result of the function scoring will be multiplied by weight) and filtering the scoring objects (only docs that pass the filter will be scored by this function).
