Most blogs have a search function. Using the search field on your blog users can retrieve information from previous posts that may no longer appear visible on the main page but are still neatly archived away in your blog. Some blogging system search engines also search the entire world wide web and not just your blog.
Notice a search field in the sidebar of this blog. Try it out to see how it works. Your students and parents will love the search feature. Truth be told, you will love it too as your blog grows and becomes really large.
