How to search for links on one web site to another

There's really no way to search for highlighted text, unless you want to search through the source code for the HTML tags. A better bet may be to use Blogger's labels.

The labels are just like tags or keywords; you can use them to organize your posts. For example, you could label posts that you want to come back to with "important," "check," etc.

To make it even easier, you could add the Labels gadget to your blog, in the sidebar or at the top or bottom. The Labels gadget shows all your labels, in the format you select, and you can click on one to show all the posts with that label.

A query like John Jack site:abc.com will search the site abc.com and return the pages that contain the words "John" and "Jack".

If you want to be more specific, use "John Smith" "Jack Brown" site:abc.com - this will return results from abc.com that contain the exact phrase "John Smith" and "Jack Brown"
