Delete search history from android settings app

In Android, it's possible to search for a specific setting by tapping the magnifying glass icon at the top right corner of the Settings app and typing. However, I haven't found a way to remove earlier search queries. There is a question how to clear this but it only works until android 6 marshmallow. Is there a way to clear the search history, or, better, to remove a specific search in android 7 nougat? I can't find search_index.db in the data folder of settings app. Where is this located now? I know it can be fixed by clearing data of settings app but I want to find the location of the search_index.db
