I forgot to say that the function buldQuery doesn't work when a string with a space is given. For example: 
my $query = buildQuery( <<EOQ );
    (OR
        (OR AUTHOR=John Nash PROFIT=90% )
        (OR AUTHOR=Matt PROFIT=80% )
    )
EOQ
print "\nQuery: $query\n";

This does not work because John Nash has a space in between. Can someone help me get it to work please?
