Cause
This is caused because the Confluence Awesome Search plugin is not longer compatible with the upgraded Confluence version, to address this miss behaviour it's necessary to remove this third party plugin.
Resolution
Go to manage Add ons page.
Search and Uninstall the plugin "Confluence Awesome Search".
Shutdown Confluence.
Start Confluence.
Try Searching again.
