Brian,
If you want a fully functioning search system I can highly recommend Zoom Search which is available in both free and paid for versions. If you are updating the search for your clients you can run as many domains as you want as it is licensed per computer not per domain.
I am using this on Murranji Photography and my own site at the moment.
It is a windows program so I run it in one of the VM's I have set up on my Mac and it works a treat.
