Emacs 筛选自动完成下拉式搜索结果

我已经设置了cedet+自动完成，并让推荐系统开始工作。但是，每当显示推荐的下拉菜单时，我希望在输入字符时过滤结果。 这是屏幕截图：

因此，当我键入

pu

时，我希望下拉菜单包含类似

push_back

的结果。我怎么知道

这是我的.emacs文件（相关部分）：

---

我想您可以使用

acisearch

。当弹出完成工具提示时，您可以通过

C-s

调用它

弹出完成工具提示（

M-x自动完成

或自动启动）

调用

ac isearch

（

C-s

）

过滤完成

知道我应该如何将ac isearch与auto complete集成吗？
