Still little overlap!
Even with four Inktomi-based databases (HotBot, Snap, MSN Web Search, and Yahoo!'s Inktomi database -- Anzwers and Canada.com do find the same hits as HotBot and are not considered here), there was a low degree of overlap even among those four. Three of the Inktomi databases included unique hits not found by any of the other nine search engines.
See the more detailed analysis of unique hits to gain a sense of how the 47 unique pages were divided among the search engines.
While decisions about which Web search engine to use should not be based on size alone, this information should be part of the decision. See also statistics on search engine size, unique hits, dead links, and the change over time.
