search highlighted text

Visually select the text you want to search.

y q / p
Enter

q/ works similarly to vanilla search / except you're in command mode so p actually does "paste" instead of typing the character p. So the above will yank the characters you're searching for, then paste them into a search.

(see :help q/)
