Hello guys,im new to perl so i got a small problem here.Glad if anyone could help.
Im building a personal search engine and i would like to use double quotes to get the exact word/words.I got stuck and didnt know where to specify the double quotes to do the action.
 
My code:
#!c:/perl/bin/perl
read(STDIN, $buffer,$ENV{'CONTENT_LENGTH'});
@pairs = split(/&/,$buffer);
foreach $pair(@pairs){
($key,$value)=split(/=/,$pair);
$value =~ tr/+/ / ;
$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
#$value=~ s/\"//g; # strip double quotes
$formdata{$key}.="$value";
}
$search=$formdata{'search'};
open(INFO, "Docs.htm")or die "Can't open file for output"; # Open db for reading
@array=<INFO>;
close (INFO);
$count = 0;
print "Content-type:text/html\n\n"; #Content Header
print <<End_of_head;
<html>
<head><title>.::Search Results::.</title></head>
<body>
<h5>You Searched for :$search</h5>
End_of_head
   if($search eq "")
{
print "Error: Please type something";
}
else{
       #Both of the words
     $search =~ s/^\s+//;
     @cut = split(/\W/, $search);
     foreach $line  (@array){
     $count++;
     if (($line =~  /\b$cut[0]\b/i ) && ($line =~  /\b$cut[1]\b/i )) {
print <<End_of_line;
<font color="Red">Line<b> $count:</font> $line <br>
End_of_line
}
}
}
      #Exact word
    if ($search eq "'")
      {
       foreach $line  (@array){
     $count++;
     if ($line =~  /\b$search\b/i ){       
print <<End_of_line;
<font color="Red">Line<b> $count:</font> $line <br>
End_of_line      
      }
      }            
}
print <<End_of_Doc;
</body>
</html>
End_of_Doc
