You can generally use Labels for a more comprehensive index of the blog contents - but both labels, and titles, index the posts based on your vision of the blog. What if you want your readers to view your blog, on their terms?
This is where the Navbar, with its search box, becomes useful.
The Navbar based search is a good choice - assuming that you don't block the Navbar, and assuming that your readers like using the Navbar.
But you're not confined to using the Search box on the Navbar - you can make your own search box, and position it where you like.
Just copy the code to the new gadget.
<form action="/search" method="get">
<input name="q" type="text"/>
<input value="Search This Blog" type="submit"/>
Having setup your new gadget, you can position it anywhere on the page. Or, you can have a search box inside a post, as I show above. That's your choice.
You can get way more fancy, for instance search multiple blogs at once, using a Google Custom Search box, but for a 5 minute blog upgrade, this is all that you need.
- Search only your blog.
- Search your blog directly, not from search engine cache. No waiting for search engine updates.
- Search private blogs, with some chance for success.
- Display search results as part of the blog display, with all blog accessories and decorations visible.
