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:

我做错了什么?我真的很感激任何意见。
