Same situation with 'mhinz/vim-grepper'

This is minimal vimrc.

And you should input :Grepper -query 'some keyword'

syntax on
filetype plugin indent on

if has('vim_starting')
  let s:pluin_manager_dir='~/.vim/plugged/vim-plug'
  execute 'set runtimepath+=' . s:pluin_manager_dir
endif

call plug#begin('~/.vim/plugged')
Plug 'ronakg/quickr-preview.vim'
Plug 'mhinz/vim-grepper'
call plug#end()

augroup MyQf
  autocmd!
  autocmd FileType qf set nobuflisted
augroup END
