I’ve installed Mac OS X 10.7 (upgrading from 10.6) and was very interested to see how the new search tokens feature would work in Spotlight. But on my Mac it doesn’t. Here’s the result of a search for files whose name contains the text “david buxton”:
Note how none of the files in that list has a name containing the text “david buxton”.
Perhaps deleting the Spotlight index would fix things. Meh.
