By default, the WordPress blog search doesn’t search Pages. If you’ve an eduBuzz blog and want it to do that, activate the Search Pages plugin.
This plugin, from http://www.internetofficer.com, extends the scope of the search to include Posts and Pages.
Just added a note on how to do this to the eduBuzz support wiki, which you can find at https://www.edubuzz.org/support
You can see an example on the Dunbar Primary Parents site, where Chris has used it effectively on the Current Classes Page to display a table of current classes.
