From your description it seems like you want the 'keyword' to be broken up at whitespace:
my @words = split /\s+/,$keyword;
my @list;
my $where = join(' OR ',
map {
my $col = $_;
map { push @list, "%$_%"; "$col like ?" } @words
} qw(mfg productID desc)
);
my $sth = $dbh->prepare('SELECT * FROM productTable WHERE ' . $where);
$sth->execute(@list);
Note the use of placeholders - the ? signs. Don't use a CGI param directly in a SQL query! *) Run your CGIs with the -T switch and untaint your data (see perlsec).
*) what happens if the keyword is something like 'foo; drop productTable; select 1 where 0' ?
