Good book or resource that talks about custom connectors and SharePoint search Integration?

Question

Do you know any good books or resources that explains how to write your own custom connector for search crawling?

I have been reading Professional Business Connectivity Services in SharePoint 2010 which talks about what I want to learn but by skipping several necessarily steps to be able to follow. I need a resource that talks about the same things but in a more step by step way.

Thanks
