If you use the counsel package and ag, I recently requested a PR and that got accepted. If you use the latest version of counsel from Melpa, the function to search in all NEWS files is now simply this: (defun counsel-ag-news (&optional initial-input) "Search for a pattern in NEWS files using ag. INITIAL-INPUT can be given as the initial minibuffer input." (interactive) (counsel-ag initial-input data-directory " -G '/NEWS'" "Search NEWS")) -- -- Kaushal Modi
