Hi everyone!
I tried what you all suggested and now my code looks like this:
open(HH, "<$PATHDATA/query04.txt");


    chomp( my @query_arr = <HH> );

close HH;


open(XX, "<$PATHDATA/multisearch_final_sorted_3.txt");
open(DD, ">$PATHDATA/query_results.txt");
my $count=0;
while ( my $line = <XX> ) {
if ($debug) {
                print MAGENTA, "LINEA:$line\n";
                    }
    for my $query_el (@query_arr) {
        if ($debug) {
                    print GREEN, "QUERY:$query_el\n";
        }
        if ($line =~ /^$query_el\]\[.*/i) {
                    if ($debug) {
                    print GREEN, "QUERY:$query_el\n";
                    print MAGENTA, "MATCH:$line\n";
                    }
                    print DD "QUERY:$query_el\n";
                    print DD "MATCH:$line\n";
                    print DD "#################";
                    $count ++;
        }
    }
}
                print DD "Entrate trovate: $count";
        
    
        
        close XX;
        close DD;

    exit 0;

Unfortunately, due to the large amount of data I have, I cannot understand if it's working, since it's not printing anything and it seems to take forever to finish.
Is there a way I can make it a little faster?
Every suggestion is really appreciated.
Thanks again,
Giu
