I just reworked an interesting idea added to this tip:

The following script means you can press Enter to toggle search
highlighting for the current word on and off (without moving the
cursor). I did not think I would want this, but it's strangely
attractive.
let g:highlighting = 0
function! Highlighting()
if g:highlighting == 1&& @/ =~ '^\\<'.expand('<cword>').'\\>$'
let g:highlighting = 0
return ":silent nohlsearch\<CR>"
endif
let @/ = '\<'.expand('<cword>').'\>'
let g:highlighting = 1
return ":silent set hlsearch\<CR>"
endfunction
nnoremap<silent> <expr> <CR> Highlighting()
Question: Can a script detect whether search highlighting is
currently active? The above uses a global variable as a
workaround
Well, you always have access to &hls as a variable, so you can do
things like
function! Highlighting()
let l:search = '\<'.expand('<cword>').'\>'
if &hls == 1 && @/ == l:search
return ":silent set nohls\<cr>"
endif
let @/ = l:search
return ":silent set hls\<cr>"
endfunction
nnoremap <silent> <expr> <cr> Highlighting()
With a little thought, one might be able to smash this into a
one-liner non-<expr> mapping, but the readability of the function
is a bit easier.
