This all started when I decided to change the URL of my blog. The problem comes with searching the blog. I know these methods to search a Blogger blog:
1. using the Navbar
2. using Search Box Gadget
3. using Google Custom Search
4. Google Search Form
Navbar
google.com/support/forum/p/blogger/thread?tid=0225b59807fc566e
When you change the URL of your blog, older posts are no longer searchable. Some have said that only the last 26 posts are searchable. I have found that any existing posts or Imported posts with date earlier than the URL change are not searchable by the Navbar. A workaround is to go to each post and change the date to Automatic, but this is not feasible for large blogs.
Search box gadget
This is similar to the Navbar, but allows for some customization. It suffers from same search problem as the Navbar.
Google Custom Search Engine
This is similar to the Navbar, but allows for some customization. It suffers from search problems as well.
Google Search Form
go to
Design > Add a Gadget > HTML/JavaScript
and add the custom Navbar
