Does its search limit to the current directory? would it search all the files in that directory? And could I use it to search files in another directory?

I guess I don't fully understand your question. When you don't pass grep a file name it "looks" for input elsewhere, for example from the standard input (keyboard) as is shown in the course video around the 2:05 time mark.
Is that what you are asking?
In terms of reading files in other directories, grep will search wherever you point it in the format:
$ grep (search term) (file name)
So, if you wanted to search for a file name outside your current directory, you would just point it there.
Make any sense?
