hybris - 需要有关灵活搜索查询的帮助以检索与分类属性之一匹配的分类属性值

Question

我是灵活搜索查询的新手，我正在尝试编写灵活的搜索查询来检索与分类属性之一匹配的分类属性值，如下所示：

select {ca.code} from {ProductFeature as pf 
join Product as p on {pf.product} = {p.pk} 
join ClassAttributeAssignment as caa on {pf.classificationAttributeAssignment} = {caa.pk}
join ClassificationAttribute as ca on {caa.classificationAttribute} =  {ca.pk}
join ClassificationClass as cc on {caa.classificationClass} = {cc.pk}
JOIN CatalogVersion as cv ON {cv.pk}={p.catalogVersion}
 JOIN Catalog as cat ON {cat.pk}={cv.catalog}} where {ca.code} = 'capacity' and {cv.version} = 'Staged'

在上面的代码片段中，我能够获取 ClassficationAttribute 的代码，但是如何获取该属性的值？
