FWIW, search.cpan.org's indexer is generally not referred to as the "CPAN Indexer", and its mostly closed-source ( see How does the CPAN indexer determin documentation )

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
