Doron Cohen commented on LUCENE-664:
------------------------------------

Hi Grant, 

For part 1, I am ok with having it after the scoring formula.

For part 2, my motivation was to make it more clear in:
  - - what's inside the sum and what's outside (as you said).
  - - what's decided at indexing time and what's still controllable at search time.
  - - how boosts and encoding/decoding play in.
  - - what's fixed and what can be modified, by subclassing, say, DefaultSimilarity.

So {indexBoost, searchBoost, normalizer} were the tools to clear this up, and also to make the formula shorter and easier to read in a glance.

Naturally, after delving so deep into it is now clear to me, but you are right, it would be good to hear from others how they like this part.

Thanks,
Doron

> This is an awesome initiative.  We need more docs that cleanly explain the inner workings of Lucene in general... thanks Grant & Steve & others!
> I have a few small initial proposed fixes, largely just adding some more description around the components of the formula.  But also a couple typos, another link out to Wikipedia, a missing closing ), etc.  I've only made it through the "Understanding the Scoring Formula" section so far.
