Subject about norm
Date Wed, 02 Jun 2010 07:19:12 GMT
in javadoc
norm(t,d)   =   doc.getBoost()  ・  lengthNorm(field)  ・   ∏  f.getBoost()
f in d named as t
whre is field come from in lengthNorm(field)?
In my option, term t may appear in a doc d many times with different fields. So
       ∏  f.getBoost()
 field f in d named as t
makes sense.
But Why there is only one lengthNorm(field) ?
does it mean that norm(t,d)=norm(t.text, t.field, d)? That's is--
every doc,every field,every term , there is a norm value ?
