I find it obnoxious that highlight search stays on until you manually turn it off. If I have edited some text after searching, 99% of the time that means I found what I was looking for and I don't need highlighting anymore. How can I make it so highlighting turns off when I edit a file? Here's what I tried, but for some reason it doesn't seem to have an effect.
augroup allfiles
autocmd!
autocmd TextChanged,TextChangedI * :nohl
augroup END
:help noh explains why this isn't working.
:noh[lsearch] Stop the highlighting for the 'hlsearch' option. It
is automatically turned back on when using a search
command, or setting the 'hlsearch' option.
This command doesn't work in an autocommand, because
the highlighting state is saved and restored when
executing autocommands |autocmd-searchpat|.
Same thing for when invoking a user function.

The basic trick is to use feedkeys and a <plug> mapping with execute(:
inoremap <expr> <Plug>(StopHL) execute('nohlsearch')[-1]
fu! StopHL()
if !v:hlsearch || mode() isnot 'n'
return
endif
sil call feedkeys("\<Plug>(StopHL)", 'm')
endfu
au InsertEnter * call StopHL()
