Finding files based on keyword or tag

All,
If you are coming from CVS world you all know that in CVS you could find files or search for files in a project based on Tag, for example if I have following file structure

Project AZ
    Directory A
       - File b
        - File c
        - File d
        - Directory B
               - File e
               - File c
               - File h

.....etc.

And in this structure after I finish code review, I could tag any specific file as "Approved" or any other meaningful name so that later I could find that file and make a build. So in the above directory structure, I could tag File c as Approved and leave rest of the files untagged. In subversion I am looking for similar feature, since CVS tag concept is gone in subversion and has been replaced with copy concept, I am just wondering if anyone knows how to achieve CVS's tag concept in subversion without using svn copy. I thought I could use subversion's keyword feature but I can add keyword in a file but later I can not find that file based on the keyword. Please help.
