Hi, I was testing the sorting by function query https://issues.apache.org/jira/browse/SOLR-1297 and I was trying something like:
http://localhost:8084/solr35/myapp/select/?wt=xml&start=0&rows=13&q.alt=my+query&sort=sum(mul(score,3),mul(num_visits,2))%20desc In this way we will be able to add little modifications to our score formula by giving weight to other numeric fields. The problem is that the score is not considered as a field inside the sorting function and it only works with numeric fields already in your index i.e sort=sum(mul(num_points,3),mul(num_visits,2))%20desc There is another way to include original score on this sort function?
