Blogger has added a function that allows readers to search for keywords inside of a blog. This is not restricted to the blog entries that are showing on the screen. The search goes back through the entire blog's archives.
I had tried installing Google's Search Engine that allows for the search inside the blog but with the Blogger templates, the Google function doesn't work.
I am glad that I now can search inside my own blog, and of course I am glad you can search inside of my blog!
You can find this function at the very top of each Blogger blog page.
