  * Integrate new package search feature
  Ignore-this: 8948d663270a60cb7a032dd114b25c41
  Old search did just substring search in the package name and the
  description and did no ranking of results.
  
  New search is keyword based (rather than substring). It looks in the
  package name (and components thereof), package sysnopsis and
  description. It uses a proper search ranking function (BM25F) and the
  results seem reasonable but needs fine tuning. Could later be extended
  to cover module names and to include package popularity.
