That seems like what I want -- boosting and not sorting. Is there a
function that will give me a bigger boost for field values closer to
zero?
The syntax could possibly change in the future, but look at the syntax in
the javadoc for parseFunction in
http://incubator.apache.org/solr/docs/api/org/apache/solr/search/QueryParsing.html
Then when using the query parser syntax, use _val_ to activate it.
So you get things like _val_:linear(myfield,1,2)
Use debug on the query admin page to see the score explanations generated.
