在Content Delivery中创建关键字列表

Question

想象一下,我有一个内容类型,它有两个类型类别的字段:一个是分类法作者,另一个是分类法主题,这两个分类法是无关的,它们可能有的唯一共同点是组件本身.

现在我们以访问者的身份访问网站,然后当访问者点击给定的作者时,我想创建一个列表,其中包含组件中存在的所有主题,这些主题也包含特定的作者.

我知道我可以创建一个查询对象,其中包含来自不同分类的两个关键字的标准,以检查它是否检索到任何值,问题是我需要为每个主题执行此操作,即作者和主题1,作者和主题2,作者和主题3等,最后它可能意味着数十个查询,我显然不想这样做.

正如我所看到的那样,分类法API无济于事,因为分类法和它们的关键词完全不相关.任何替代品？

根据 Ram G 的评论，并以实时内容中的代码示例为起点，我已经验证了以下解决方案的工作原理：

        }

        private static string[] GetComponentUris()

        private static Keyword[] GetKeywordsFromKeywordUris(TaxonomyFactory taxFactory, String[] contextKeywordUris)

            return contextKeywordArray;
