Cannot find few files in alfresco installation directory

I installed Alfresco Community edition 3.4d inorder to give hit highlighting. I am following this particular blog http://aymen-s.blogspot.in/. But I cannot find few files mentioned in the blog

These are all source code ,install Alfresco Community will not install them. Why do you want to find those files?

I need them to provide hit highlighting, do I need to manually write these files?

If you want to do according this blog http://aymen-s.blogspot.in/,you'd better download alfresco source code. Because it need you to modify existing alfresco kernel code.
you can download source code from  Alfresco SVN server.
