问题描述
Query.QueryOperator.AND_Field我们在 Tridion R5.3 VBscript 模板中使用了这种方法，并且效果很好.最近，在迁移到 Tridion 2011 SP1 时，我们尝试使用此方法，但它不起作用.我们了解到此方法在新的 tridion 版本中已弃用.
Query.QueryOperator.AND_FieldWe were using this method in Tridion R5.3 VBscript templates and it worked well.Recently , while migrating to Tridion 2011 SP1, we tried using this method, but it doesn't works.We understood that this method is depreciated in new tridion versions.
根据论坛中的一些帖子，我们还在 CD_Storage_Conf 中启用了以下几行:
As per some posts in Forum, we also enabled the following lines in CD_Storage_Conf:
<SearchFilter Name="SearchFilter" Class="com.tridion.broker.components.meta.MsSqlSearchFilterHome" defaultStorageId="defaultdb"/>
<Item typeMapping="Query" storageId="defaultdb"/>
问题是，'Query.QueryOperator.AND_Field' 方法的替代是什么?我们如何在 C# 中使用这个过滤器?如何使用支持 API 文件中提到的 Broker 查询机制?
The question is, what is replacement of the 'Query.QueryOperator.AND_Field' method? How can we use this filter in C# ?How to use the Broker Querying Mechanism mentioned in the support API files?
谢谢.
推荐答案
在 SDL Tridion 2011 Content Delivery 中，您可以创建一个 Query 对象并向其添加一个 Criteria 对象使用 setCriteria 方法.Query 对象ONLY 接受一个 Criteria 对象，但该 Criteria 对象可以反过来引用其他 Criteria 对象树结构.
In SDL Tridion 2011 Content Delivery, you create a Query object and add a Criteria object to it using the setCriteria method. The Query object accepts one Criteria object ONLY, but that Criteria object can in turn reference other Criteria objects in a tree structure.
有关使用 AND 和 OR 运算符创建查询过滤器的很好示例，请参阅SDL LiveContent 中的 SDL Tridion 2011 SP1 文档中的创建过滤器.
For a good example of creating a Query filter using both AND and OR operators, see Creating a filter in the SDL Tridion 2011 SP1 documentation in SDL LiveContent.
// Schema has ID of either 511 (Article) or 34 (Press Release).
ItemSchemaCriteria IsArticle = new ItemSchemaCriteria(511);
ItemSchemaCriteria IsPressRelease = new ItemSchemaCriteria(34);
Criteria IsArticleOrPressRelease = CriteriaFactory.Or(IsArticle, IsPressRelease);
// Type of the item is 16 (Component).
ItemTypeCriteria IsComponent = new ItemTypeCriteria(16);
// Both of the above conditions must be true
Criteria AllCriteria = CriteriaFactory.And(IsArticleOrPressRelease, IsComponent);
// Add these criteria to a query
Query MyQuery = new Query();
MyQuery.Criteria = AllCriteria;
