过滤自动完成下拉搜索结果

Question

我已经设置了 cedet+auto complete 并让推荐系统正常工作。但是，每当显示推荐下拉菜单时，我希望在输入字符时过滤结果。 这是屏幕截图：

所以当我输入pu 时，我希望下拉菜单包含push_back 这样的结果。我怎么得到它？

这是我的 .emacs 文件（相关部分）：

;;; yasnippet
;;; should be loaded before auto complete so that they can work together
(require 'yasnippet)
(yas-global-mode 1)
(defun my:ac-c-header-init ()
  (require 'auto-complete-c-headers)
  (add-to-list 'ac-sources 'ac-source-c-headers)
  (add-to-list 'achead:include-directories '"/usr/include/c++/4.8"))

(add-hook 'c++-mode-hook 'my:ac-c-header-init) 
(add-hook 'c-mode-hook 'my:ac-c-header-init) 




(add-to-list 'load-path "~/.emacs.d/")
(require 'auto-complete-config)
(add-to-list 'ac-dictionary-directories "~/.emacs.d/ac-dict")
(require 'auto-complete)
(ac-config-default)
(setq ac-auto-show-menu t)

我想你可以使用ac-isearch。弹出完成提示时，您可以通过C-s 调用它。

1. 弹出完成工具提示（M-x auto-complete 或自动启动）
2. 调用ac-isearch(C-s)
3. 过滤完成
