Problem

无法在Finder还是Alfred中，都无法搜索到一个已经存在的文件。

Solution

1.关闭聚焦（spotlight）

sudo mdutil -a -i off

2.不加载控制聚焦参数的文件

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist

3.重新加载控制聚焦参数的文件

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist

4.打开聚焦

sudo mdutil -a -i on

sudo mdutil -E /

这里 -E 表示”Erase and rebuild index”（删除并重建索引），/ 表示从 root 目录开始（重建所有文件夹的索引）
