Thank you Bryan for advices.

Applying that example
" From http://andrewvos.com/2016/09/14/writing-async-jobs-in-vim-8

I have done this code.
function! BackgroundCommandClose(channel)
" Read the output from the command into the quickfix window
execute "cfile! " . g:backgroundCommandOutput
" Open the quickfix window
copen
unlet g:backgroundCommandOutput
endfunction

fun! utils#Search(args) "{{{
"
"
"
let prgPath = expand("$vimruntime")."/rg.exe"
if !file_readable(prgPath)
echoerr "rigrep tool not found in ".$vimruntime
return -1
endif

let l:args = empty(a:args) ? expand("<cword>") : a:args
let cmd = prgPath . ' -n ' . l:args


" Async func
let g:backgroundCommandOutput = tempname()
let j = job_start(cmd, {'close_cb': 'BackgroundCommandClose', 'out_io': 'file', 'out_name': g:backgroundCommandOutput})
endfu
command! -bang -nargs=* -complete=file Search call utils#Search(<q-args>)


It works very well in background and copen the cfile well formatted.

Maybe you can advise me how optimizing BackgroundCommandClose func declaration in order to declare it within the utilsSearch func.

But thank for your advices.
