I have Safari set to not remember my search history i.e. private browsing, as I dont like being confronted with a massive list of stuff as soon as i type the first letter of a search. Its just quicker to keep typing. However if you ask Siri to search the web for something that search is retained in the history list. How can you stop it? I know how to clear it manually but how can i stop it being added in the first place?
