Q: The bookmarks and history search suggestion when I type a letter won't delete a vulgar search even after clearing history

Hello there, Jdaddy_1.

It sounds like you've started on the right track to correcting the issue with your Safari browser's search history. The following Knowledge Base article offers additional steps to review:

Safari web settings on your iPhone, iPad, or iPod touch - Apple Support

Clear information from your device

To clear your history and cookies from Safari in iOS 8, tap Settings > Safari > Clear History and Website Data. In iOS 7 or earlier, tap Clear History and tap Clear Cookies and Data.

To clear other stored information from Safari, tap Settings > Safari > Advanced > Website Data > Remove All Website Data.

To visit sites without leaving a history, turn on private browsing.

Thanks for being a part of Apple Support Communities.

Kind Regards,
