  I think that depends on how approximate it is and how the results are
ranked.  Obviously this will take a lot of tuning; my main point is that
I want to implement the most useful string-based search I can, and
that's not going to just search names. :-)

  Well, this won't impact anything other than "search", and it may
actually make things faster (I'll probably use an index on the package
cache, and I may even adjust the search interpreter to support some more
efficient modes of operation...)
