in thread Addional "year" matching functionality in word matching script

The keys of %csv2hash are the lines:

for (@csv2) { # for data in @csv2 array my ($title) = $_ =~ /^.+?,\s*([^,]+?),/; $csv2hash{$_} = $title; }

Here, $_ (the current line) is used as a key into %csv2hash.

    What does this bit of the script do?  my @matches   = ( $value=~/\b$word\b/ig ); specifically the  \b  \b/ig bits?
      See perlre for explanation.

      \b matches "word boundaries", but in a special meaning of "word". /i makes the matching case insensitive, and /g makes it global, i.e. it matches as many times as it can, and returns all the matching substrings.

      ($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord }map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,
        Ok, i'm near the end of the script now. In this bit, I can see why the script prints out the line from $csv2, but I can't understand how it prints out the line from csv1. I can't see where it gets this information.
        if ($count >= $desired) { print "$csv2\n"; ++$matched; } } print "$_\n\n" if $matched;
        I can see the:
        print "$_\n\n" if $matched;
        bit somehow contains the information from csv1, but I can't see anything in the script which suggests why this would be?
