Boost fileds at indexing ot query time
Hey there,
Don't know if I shoud ask this in here or in Lucene Users forum...
I have a doubt with field boosting (I am using dismax). I use document
boosting at index time to give more importance to some documents. At this
point, I don't care about the matching, just want to tell solr/lucene that
that docuemtns are more important than the others.
In another hand, I give field boost at query time to some fields because I
want to give more importance to the match in that field than in the others.
Until here everything clear... but I am missing the concept of field boost
at index time... waht is it used for?

>From Hossman:
"index time field boosts are a way to express things like 'this documents
title is worth twice as much as the title of most documents'. Query time
boosts are a way to express 'I care about matches on this clause of my query
twice as much as I do about matches to other clauses of my query'.
