There are so many good search engines out there, and some seem to be better than others for genealogical research. Google does a pretty good job of finding appropriate results, but I also like Clusty because of the ability to sort the results by type (marriage, vital, biography, etc), and also by what kind of sites they are (.org, .gov, .us, .net, etc). What other search engines have you found that give good appropriate results for your genealogy searches?
