hmm, well, I see what it printed but I'm not sure if I defined the empty-string key in the hash as you have asked me, did I do it correctly?.

If I add a space in between the tick marks then the hash returns 

this is INDEX   =>bernini

If no space between the ticks then match hash returns nothing.

can you explained why even when the empty string(space in it) ' ' returns the key when there's not space in the $string that's being checked against??

ok, I am have to read more on the index.

I appreciate the well detailed explanations

thank you

my $string = 'abcdefghijk'; 
my %match = (' '=>"bernini",bc => "Michelangelo", efg => "Raffaello",d
+e => "Caravaggio",ijk => "Tintoretto",hij=>"Leonardo",);

foreach $art (keys %match){
    print "this is INDEX $art =>",join(',',$match{$art}),"\n", if inde
+x $string,$art;
    }
