saves google web searches on browsers then deletes after a few days or open other apps

hi when i search for anything on google.co.uk either an web, image or video search it automatically saves what i have searched but after a few days or when i open any apps which are related to google then open back any web browser on android for example dolphin that's the one i mostly use it somehow had deleted the search history that i searched. I am not signed in to google though. is there a way to fix this so that i can keep a history of what i have searched for without having to type my searches back in again thanks. here is a screenshot showing what i mean
