Searching in Google Earth is still atrocious. Even when you have Oceans activated, typing in "Titanic" into the search field will get you nowhere. If you adjust the term to "Titanic shipwreck," your results seem to depend on your most recently searched locations. After looking at San Francisco, searching for "Titanic shipwreck" showed me a list of shops and restaurants that had "Titanic" in the name. After closing and re-starting Google Earth, and searching for "Titanic shipwreck" again, the globe panned over to the correct part of the North Atlantic but did not zoom in.
