I considered that, but assumed we'd get the values wrong at first and
have to do a lot of tinkering before we got it right. Is there a good
way to do this at query time, or do you really need to do this when
loading? It would be feasible to boost at load time, but recovery
times from bad decisions are longer than I was hoping for.
The other option is to use a function query on the value stored in a
field (which could represent a range of 'badness'). This can be used
directly in the dismax handler using the bf (boost function) query
parameter.
