Simply install this package through from the concrete5 marketplace and the new templates will be available under 'Custom Templates' for the core search block.
These templates will probably work with concrete5 versions back to 5.4.1, but have not been tested to do so.
The code in the templates is just the core search block code, but with chunks of it removed. There is no original code in these templates at all!
If you find any issues with the code (other than how I have cut it), please direct them to the bug tracker on concrete5.org and the core block on Github!
