It's spooky. Tim
I use Google quite a bit in researching various topics for a discussion forum, and it's always amazed me how Google will return a different list of hits for the singular and plural forms of the same word. And yet, despite seeming to be very particular in that respect, it's also amazed me how Google will return a very similar list of hits for two words, one of which is spelled correctly, and the other is not, and even if you really hash the spelling it will offer the correct spelling. e.g. "widget" and "widgets" return a different set of hits, whereas "widget" and "wijit" might return the same or very similar set of hits, and when you use "wijit", Google will ask "did you mean widget?"
