duplicate content

[jetlag]

hello
Do i need to put in my robots.txt for every subdirectory?
disallow: .../directory/subdirectory1?s=A
disallow: .../directory/subdirectory1?s=R
disallow: .../directory/subdirectory1?s=H
disallow: .../directory/subdirectory2?s=A
disallow: .../directory/subdirectory2?s=R
disallow: .../directory/subdirectory2?s=H
etc.

i did a search for my directory and i saw 3 listings for the same subdirectory

You could turn off sorting. Personally, I have had no problems with duplicate content in my directories.
