Some may be interested to know that there is another Perl article over at IBM developerWokrs:

'Use Perl and a vector-space search engine to search and display records from your Lightweight Directory Access Protocol (LDAP) database. Use inflected letters and numbers to create a useful vector space from structured LDAP data. And compensate for typographical and spelling errors automatically while showing the most appropriate match for any query entered.'

As usual, there is a feedback form at the bottom of the page.
