function queries scope

Hi,

I need to use the function queries operations with the score of a given
query, but only in the docset that i get from the query and i dont know if
this is possible.

Example:

q=shops in madrid    returns  10000 docs  with a specific score for each doc

but now i need to do some stuff like

q=sum(product(2,query(shops in madrid),productValueField) but this will be
return all the docs in my index.


I know that i can do it via filter queries, ex, q=sum(product(2,query(shops
in madrid),productValueField)&fq=shops in madrid but this will do the query
two times and i dont want this because the performance is important to our
application.


Is there other approach to accomplished that=


Thanks in advance,

Thanks, but its not what i'm looking for, because the BoostQParserPlugin
multiplies the score of the query with the function queries defined in the b
param of the BoostQParserPlugin. and i can't use the edismax because we have
our own qparser. Its seems that i have to code another qparser.


Thanks Yonik anyway,

One way is to use the boost qparser:
http://search-lucene.com/jd/solr/org/apache/solr/search/BoostQParserPlugin.html
q={!boost b=productValueField}shops in madrid

Or you can use the edismax parser which as a "boost" parameter that
does the same thing:
defType=edismax&q=shops in madrid&boost=productValueField
