Hi Gian Marco,
I don't know if it's possible to exploit documents' boost values from
function queries (see http://wiki.apache.org/solr/FunctionQuery), but if
you store your boost in a search-able numeric field, you could either :
do
q=*:* AND _val_:"your_boost_field"
if you're using default query;
or
q=*:*&defType=edismax&bf=your_boost_field
if you're using edismax.
That will give scores to a MatchAllDocsQuery (*:*) .
Hope this helps,

Hi Ahmet,
thanks for the answer.
I'm really suprised because I always thought docBoost as a kind of sorting
tool.
And I used in that way, I'm giving big boost to the documents I want back
first in search.
Do you think there is a trick to force the usage of docBoost in my special
case?

Subject: docBoost with "fq" search

Hi All,
I'm seeing strange behavior with my Solr (version 3.4).
For searching I'm using the "q" and the "fq" params.
At index-time I'm adding a docBoost to each document.
When I perform a search with both "q" and "fq" params
everything works.
For the search with "q=*:*" and something in the "fq", it
seems to me that the docBoost in not taken into
consideration.
Is that possible?
Yes possible.
FilterQuery (fq) does not contribute to score. It is not used in score
calculation.
MatchAllDocsQuery (*:*) is a fast way to return all docs. Adding
&fl=score&debugQuery=on will show that all docs will get constant score of
1.0.
