You should already assume that google and pretty much any site logs your IP whether you are using incognito or not. You should also assume that any time you log in to gmail your IP is noted. It's extremely basic to do a db search for all gmail accounts that have been accessed by a given IP. I meant if you do not login to Google and do a search in incognito mode, is that history stored? I can delete my history if I'm logged in. But there is no way to delete history by IP. It seems 'safer' to in fact use your logged in Google account to search.
