First, please, instead of including your entire data set, whittle it down to an interesting subset.

Second, time for some Perl cleanup. Perhaps along the way we'll find your bug. 

foreach(@search)
{
  # We'll put the cleaned-up URL here temporarily.
  # We could do a push directly, but this will make
  #   debugging easier.
  #
  my $ready;

  # You said you wanted to throw out mailtos
  #
  /^mailto:/ and next;

  # "if ($_ !~ /^http:\/\//gi)"
  #
  # /g is meaningless here; the caret can only match once.
  # "$_ !~ /.../" is a long way of saying "!/.../".
  # Pick your quotes to avoid Leaning Toothpick Syndrome.
  # And are you sure you want to start your if-else with
  #   a negative test?
  #
  if (!m[^http://]i)
  {
    # "if ($_ !~ /^#/g)"
    #
    # Same as above
    #
    if (!/^#/)
    {
      $ready = "$base$_";
    }
  }
  else # m[^http://]
  {
    # "if ($_ =~ /^\#/g)"
    #
    # But the first character can't be "#" because
    #   at this point we know it's "h"!
    # Shorten; /g useless
    #
    if (/^#/)
    {
      $ready = "$url$_";
    }
    else
    {
      $ready = $_;
    }
  }

  if (not defined $ready)
  {
    print "$_ was lost!<br>\n";
    next;
  }

  print "$_ becomes $ready<br>\n";  # For debugging
  push @search_ready, $ready;
}

Looks like we found the bug. I'm not quite sure what you're going for with the #'s, so I haven't tried to fix it. I highly suggest using positive tests in your if-elses. It tends to be less confusing.
