How to boost a field with another field's value?

[smita <ne...@gmail.com>]

I have 2 fields in my schema - e.g. 

long field "field1" and long field "field 2".
I'd like my boost query to be such that field1 is boosted by the value of
field 2 for each document.
What should the query time boost for this look like? I was able to do this
using Index time boosting with the DataImportHandler, but couldn't figure
out how to do this using query time boosting.

Thanks!

Actually I have a title field that I am searching for my query term, and the
documents have a rating field that I want to boost the results by, so the
higher rated items appear before the lower rated documents.

I am also boosting results on another field using bq:

q=summer&df=title&bq=sponsored:true^5.0&qf=rating^2.0&defType=dismax

However, when I use qf to boost the results by rating, Sorl is trying to
match the query in the rating field. How can I accomplish boosting by rating
using query time boosting?

See "Function Query":
http://wiki.apache.org/solr/FunctionQuery

If you are using the dismax or edismax query parser you can use the "bf" 
request parameter.

e.g.,

    q=foo&bf="ord(popularity)^0.5 recip(rord(price),1,1000,1000)^0.3"
