:noautocmd lvimgrep /hello/gj **/* - grep through all files recursively for 'hello' and put results in location list local to current window
                                   - the noautocmd switches off autocommands during search to make the grep much faster (but will disable highlighting if you jump to first match automatically)
                                   - the g option will return all matches instead of just one per line
                                   - the j option will not jump to the first match automatically
