  • public class LuceneCategorySearchEngineScoring
extends java.lang.Object
    Provides default implementation for scoring of publication result found through LuceneCategorySearchEngine.

    To override this class and provide your own implementation :

    1. Create a class extending LuceneCategorySearchEngineScoring
       public class MyLuceneCategorySearchEngineScoring extends com.jalios.jcms.search.LuceneCategorySearchEngineScoring {
 
   public float getPublicationNewScore(QueryHandler qh, QueryResultSet resultSet,
                                              Category cat, float catScore, float maxCatScore,
                                              Publication pub, float pubScore, float maxPubScore,
                                              boolean isNewResult) {
     return isNewResult ? 42f : pubScore;
   }
 }
    2. Declare your class in the following JCMS property :
       hook.cat-search-engine.scoring.class: com.example.jcmsplugin.search.MyLuceneCategorySearchEngineScoring
