If $data is an array ref, then "--Search using content--" is just $data->[2] ... is that all you need? (i.e. i assume the ->search method exist and aren't just pseudocode)
For debugging, try use Data::Dumper; die Dumper $data; so you can see what $data looks like.

I also suspect that my $data = should be my ($data) = but i can't say w/o knowing what the ->search() method returns .. if it returns an iterator (e.g. Class::DBI->search does) in scalar context, then you wan the parens to force array context and just get the first element. (I also note that your second call to a ->search() is in array context since it's my @results =, but is consistent w/my suspicion)
