如果我有这样的包树：
com.foo
com.foo.bar
com.foo.bar.baz
然后我在package-info.java中添加com.foo文件，并在com.foo包中添加注释，注释也会应用于子包com.foo.bar和com.foo.bar.baz（依此类推）？或者我是否需要使用相同的注释在每个package-info.java中创建另一个SearchVector = c('Berlin, 'Amsterdam', San Francisco', 'Los Angeles') ...
g$Message = c('This is the first mail from paris. Berlin is a nice place', 'This is the 2nd mail from San francisco. Beirut is a nice place to stay', 'This is the 3rd mail. Los Angeles is a great place') ...
？
