I wonder if there are queries or use cases we can support that *aren't*
already better handled by google. Granted, users of private wikis can't
simply use the 'site:' trick to reuse Google search results -- but users of
private wikis also probably don't need superduper scalability.
Trying to brainstorm here, not start a flame war. What sorts of useful
searches could we excel at? (Maybe these are searches/use cases that will
facilitate editor engagement?)
