Searching a Hash Can't Post

I have a Quick (Maybe not so Simple Question).

I am wondering how to search for a word/sentance in a hash, so that if it finds the word/sentance it will return the hash KEY's to the user.

I have been having problems with this and hope someone can give me an Example to learn from.

Thanks for the help, Kao

This depends entirely on how your hash is set up. Are the values in the hash long paragraphs? If so, you might want to do something like:

<BLOCKQUOTE><font size="1" face="Arial,Helvetica,sans serif">code:</font><HR>

my @results;
while (my ($k,$v) = each %hash) {
push @results, $k if index($v,$sentence) > -1;
