How many different search engine database engines do we have available right now?
There are hundreds of different search engines. Many of them don't have their own engine and simply depend on other search engine database. Many are simply an interface allowing you to search multiple search engines..
So who have their own database?
I'm not even sure Yahoo!, Google and Altavista are completely indepedent of each other when it boils down to database.
