我正在使用更改日志增量爬网方法编写自定义索引连接器。

我正在使用来自http://msdn.microsoft.com/en-us/library/ff625800%28v=office.14%29.aspx的示例并尝试为我更改它。

我的模型有下一个原型：IdEnumerator、ChangedIdEnumerator、DeletedIdEnumerator、SpecificFinder、Finder、StreamAccessor

如果我开始完全爬网，将调用 IdEnumerator、ChangedIdEnumerator、DeletedIdEnumerator。

第一个问题：SpecificFinder 没有被调用。

如果我开始增量抓取，将调用 ChangedIdEnumerator 和 DeletedIdEnumerator。

DeletedIdEnumerator 正在工作：具有已删除 ID 的项目将从索引中删除。

第二个问题：ChangedIdEnumerator 不起作用。我返回更改后的 ID 后没有任何反应。

现在 crowl 日志中有错误。

我的模型在这里：

我最近在我的自定义 BCS 连接器中遇到了类似的问题（未调用 SpecificFinder）并设法解决了它。在我的场景中，我有两个实体（父实体和子实体），SpecificFinder 只为父实体调用，但不为子实体调用。事实证明，这个问题与我构建“访问 URI”的方式有关。最初的 URI 是这样的：

<protocol>://<entity_name>/<entity_id>

我的起始 URL（在内容源定义中指定）是“假”父实体的 URL（没有任何 ID）：

<protocol>://<parent_entity_name>

但似乎 SharePoint 爬网程序以与 Web URL 相同的方式处理访问 URI，并按内容源定义中指定的 URL 路径应用过滤器。换句话说，就我而言，它只会抓取与以下模式相对应的 URI：

<protocol>://<parent_entity_name>/*

在我将访问 URI 格式更改为

<protocol>://root/<entity_name>

并将内容源定义中的起始 URL 设置为

<protocol>://root

一切都开始正常工作。
