Welcome to WebmasterWorld Guest from 184.108.40.206
I know this feature of correction was observed last December (as a test?) but it is now widely seen.
(also in Japan. ;-))
Same with the idiotic "typo" correction.
To get accurate results you have to type "word" or +word to force goggle to actually search for what you type.
I just searched for a specific person, where there are about 100 results total, but the inital Google page shows over a million. Unsophisticated users would never find what they are looking for.
