For all the amateur Google anthropologists and archaeologists out there, I've uploaded the lastgoogle query data for May (899 total queries) to the lastgoogle wiki:
lastgoogle_queries_200605.sql.gz (58 kb)
It's a gzipped mysql file generated in phpmyadmin.
It offers some insight into the type of basic data Google probably collects when you use their search engine. I'd guess Google probably collects a lot of other data, too, like your ip address and browser info and who knows what else.
