That means the value of $search was undef.
That means that it could not parse or open the BLAST report.
I repeat the line that I put in my earlier email which you ignored.

# your line
my $search = Bio::SearchIO->new( ..... );

# then check if it was successful!
die "could not open blast report" if not defined $search;
