Chrome will show security warnings on your site.

Starting October 2017, Chrome (version 62) will show a “NOT SECURE” warning when users enter text in a form on an HTTP page, and for all HTTP pages in Incognito mode.
The following URLs on your site include text input fields (such as < input type="text" > or < input type="email" >) that will trigger the new Chrome warning. Review these examples to see where these warnings will appear, so that you can take action to help protect users’ data. This list is not exhaustive.

Принуждают переходить на https. Хотя на сайте всего-то ввод строки поиска, которую сложно считать вврдом персональных данных. Смысл заморачиваться?
