Hi, looking at your REs I have a couple of suggestions: 

    $text =~ s/\[.*?\]/ /g;
    # you can lose the .*? by using [^\]]* which save the RE engine ba
+cktracking
    # $text =~ s/\[[^\]]*\]/ /g;

    $text =~ s/[.,?"':&()!-]/ /g;
    $text =~ s/[^\w ]//g;

    # you need a /m to make this match
    # here
    # and here
    # and here
    # ie this will only match the very begining of the string
    $text =~ s/^\s+//;
    # ditto
    $text =~ s/\s+$//;

    $text =~ s/\s+/ /;
