Question

I am aware that it is possible to configure vim to highlight all matches for the searched word.

But, is it possible to highlight the entire line(s) on which the searched for word is found? If so, how?

Answer 1

The exact solution depends probably on your goal:

Do you want to make the matched lines stand out a little more?

Do you want to know the line numbers for further use?

Do you want to act directly on those lines?

You could use the quickfix window to list the lines containing a match:

:vim! foo . | copen

You could use the :global command to list or act on every line containing a match:

:g/foo<CR>          " list the lines
:g/foo/<Ex command> " act on each line
