OK. What we should do then is to delegate caching to another class family,
say 'QueryCache'. Let's put there an abstract mother-of-all-the-caches with
virtual Lookup(signature) and Add(signature, result), and that's it.
Initially, I'll contribute with a VolatileCache derived from it :)

I'm not sure I'm understanding that. The query evaluation system works with
word references. We won't be able to query things as 'title:*' or '* not
foo' if we haven't word matches to filter, just doc ids. Isn't that the
idea?
