 ## 主要命令
 
 - `build` 编译并安装 Go 包以及其依赖包：该命令从底层调用 `go install` 命令，如果为 main 包，则会将可执行文件从 `GOPATH` 中移至当前目录，可执行文件的名称是由 `go install` 默认指定的当前文件夹名称。 
+- `search` 通过关键字在 [Go Walker](http://gowalker.org) 数据库中查找相关包。
 - `install` 下载并安装 Go 包以及其依赖包：您无需安装像 git、hg 或 svn 这类版本控制工具就可以下载您指定的包。该命令也会自动下载相关的依赖包（当您使用集合或快照下载时，不会自动下载依赖包）。目前，该命令支持托管在 `code.google.com`、`github.com`、`launchpad.net` 和 `bitbucket.org` 上的开源项目。 
 - `remove` 删除 Go 包及其依赖包：该命令可删除 Go 包及其依赖包（当您使用集合或快照删除时，无法自动删除依赖包）。
+- `check` 检查当前包的依赖包是否全部安装，如果发现未安装的依赖包会提示您是否选择安装。
