Shameless plug and one that will likely embarrass me in the end
(editors note: notice how that big word ends? - time will tell)
ANYWAY -
I have added a CGI only personal Google search to my site. It is in dev mode right now and is open to be ridiculed - go ahead, you know you want to
!
I only have 70 different sites in my indexer at the moment but will (slowly) be adding more. I am trying to figure out the Google tool to properly create refinement links and so on. The Google type landing page and search footer seem to be problematic as well but that is likely due to not knowing what I'm doing.
Also, you can 'break-out' and get the thing to search outside my list even though it is not supposed to work that way. I can do it to the example sites from the developer forums so that one is not on me.
