DocumentHelper.GetDocuments（）。InCategories（）API方法未按预期工作

Question

我正在尝试获取具有指定类别的给定类型的文档。这是我的代码：

var inCategoryDocuments = DocumentHelper.GetDocuments("XYZ.MyType").InCategories("CategoryCodeName");

此查询的结果：

SELECT * FROM View_CMS_Tree_Joined AS V WITH (NOLOCK, NOEXPAND) INNER JOIN xyz_MyType AS C WITH (NOLOCK) ON [V].[DocumentForeignKeyValue] = [C].[MyTypeID] AND V.ClassName = N'xyz.MyType' LEFT OUTER JOIN COM_SKU AS S WITH (NOLOCK) ON [V].[NodeSKUID] = [S].[SKUID] WHERE ([DocumentCulture] = N'en-EN' AND 0 = 1)

看起来这个API方法（.InCategories（））什么都不做，或者我缺少什么？
