in reply to How to sort Hashes of Hashes and print results in a file

Well, by definitions hashes are unordered collections. You could e.g. get an ordered list/array of key/value pairs or whatever, but they won't be hashes. Or you could use Tie::Hash::Indexed or Tie::IxHash to get ordered hashes.

Regarding your questions, I hope you can re-phrase them.

    Ok let me rephrase. Here is my hash
    %hash{
a => {doc1=>'2.0',
      doc2=>'4.5',
      doc7=>'3.0'
     },
b => { doc2 => '3.5',
       doc10 => '6.5',
       doc7 => '11.4',
       doc20 => '0.5'
     }
}

    Now for 'a' I need to retrieve top 2 doc with highest value.
    In this case it will be 'doc2' and 'doc7'
    In case of 'b' it will be 'doc7' and 'doc10'
    Number of docs will differ in 'a' and 'b'.
    Does this clarify my question

      I've run my script and the result was: 
      -> a
--> doc2: 4.5
--> doc7: 3.0

-> b
--> doc7: 11.4
--> doc10: 6.5
