Subject [jira] Commented: (LUCENE-664) [PATCH] small fixes to the new scoring.html doc
Date Tue, 03 Oct 2006 01:53:22 GMT
    [ ] 
Doron Cohen commented on LUCENE-664:

Two quick questions:

> I think 'norm' is a good term for the product of lengthNorm(d) and 
> field boost. That's what it is called consistently in the code and API. 
> This quantity is represented in two places, but seems like a logical 
> candidate for the sort of factoring done here. 

Norm would also Include the doc boost, right?
So this means replacing *indexBoost* with *norm* ?

> This could be placed to the left of the sigma, since it does not depend on t. 

I think that norm depends on the field name and there may be terms of more than one field
in the query.?

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"
