First of all, they're completely different algorithms. Google search relies on user input to suggest correct spellings. So people have searched posive, got it wrong, then typed positive.

The Short Answer

First of all, they're completely different algorithms. Google search relies on user input to suggest correct spellings. So people have searched posive, got it wrong, then typed positive. The algorithm has now linked the two words, and from then on it makes the suggestion (stored on the google server). Chome spell checker is a bit different, it just uses a search function, and matches according to matching letters. It's using an offline database, rather than online – just a list of spelled words. for the record, i use the aussie dictionary on firefox, and it suggested positive. 🙂
