Select all checkboxes highlighted on a webpage during ctrl+F on google?

I need a way to check all checkboxes that are highlighted during a google ctrl+f search on a page. So let's say my webpage has multiple instances of entries such as 1, 2, 3, 4 .... So when I search for 1 using ctrl+f on the webpage and it highlights ten entries for 1 with checkboxes next to these entries, I need a way to select all checkboxes next to that entry. Any help will be greatly appreciated!
