使用＆＃34; honda car＆＃34;在vespa应用程序中提交Exception in thread "main" java.lang.IllegalStateException: Score corruption: the workingScore (-17hard/0medium/0soft) is not the uncorruptedScore (-20hard/0medium/0soft) after completedAction ([TaskAssignment-5 {Machine-1([023]) -> Machine-1([023])}, TaskAssignment-5 {TimeGrain-2 -> TimeGrain-2}]): The corrupted scoreDirector has no ConstraintMatch(s) which are in excess.

我有一个外部引擎，可以根据查询为查询功能和排名功能（权重）提供支持。我非常了解查询配置文件，但如果我想用＆amp; feature1 =＆＃34; value1＆＃34;＆amp; feature2 =＆＃34; value2＆＃34;来增强查询，请使用它。如何与搜索者或任何其他组件一起使用？

我们在Vespa的Query类中有一个方法http://localhost:8080/search/?query=honda car。它是否为每个非结构化查询调用，换句话说，非结构化查询是否转换为YQL然后被索引命中？

Answer 1

要通过查询传递排名功能，请编写一个Searcher，将其添加到Query.getRanking（）。getFeatures（）：

public class FeatureAdder extends Searcher {
    @Override
    public Result search(Query query, Execution execution) {
        Map<String, Double> features = lookUpFeaturesFromExternalStore();
        features.forEach((name, value) -> query.getRanking().getFeatures().put("query(" + name + ")", 
                                                                               String.valueOf(value)));
        return execution.search(query);
    }
}

现在，您可以使用“query（name）”在排名表达式中访问这些值。

非结构化查询是否会转换为YQL，然后会被索引命中？

YQL只是一种外部表示语言。查询（非结构化或非结构化）被解析为Query.getModel（）。getQueryTree（）下的对象表示。如果您想以编程方式（从搜索者）修改查询，那么您应该处理这个问题。

扩展查询具有外部驱动的排名和查询功能？
