Use `find:
使用`查找：
find /home -type f | xargs grep SymbolSetThree
The same result can be achieved by using the -execargument to find(instead of xargs).
通过使用-exec参数 to find（而不是xargs）可以获得相同的结果。

You are close, you just need the -rswitch to have your command working properly.
你很接近，你只需要-r开关让你的命令正常工作。
grep -r "SymbolSetThree" /home
will do the trick.
会做的伎俩。

For this kind of tasks I really like ack-grep, is programmer oriented (only source files, .py .rb .c .sh) but with -a it looks for all kind of files.
对于这类任务，我非常喜欢 ack-grep，它是面向程序员的（只有源文件，.py .rb .c .sh），但使用 -a 可以查找所有类型的文件。
ack-grep -a "SymbolSetThree"
