Multi Layered max() Solr
The Solr "qf" parameter works as follows:
Let's say I have: query = "sid" and qf = [field1, field1_edge, field2, field2_edge].
The Solr score is calculated as follows:
max(f1, f1_e, f2, f2_e) + tie * (sum of other 3 fields) where: "tie" lies in [0,1]
Let's call: winner1 = field with max(f1, f1_e) and
winner2 = field with max(f2, f2_e)
I would like to score a given query in Solr as follows:
score1 = winner1_score + tie_1 * loser1_score
score2 = winner2_score + tie_1 * loser2_score
final score = score1 + tie_2 * score2
Effectively, I want to apply qf in two layers (taking tie_1 = 0 and tie_2 = 1).
What are my options to implement this idea of relevance? I think neither "qf" parameter nor function boosts support this.
Thanks!

Are you asking how you can use the separate scores as calculated for each field, or how you can use themax()function with the values (as stored in the fields namedfield1_score, etc.) from multiple predefined fields as the score?

@MatsLindh Basically, I am interested in using scores of different fields to compare them in discrete steps. For example, in step 1, I want to compare scores from 2 differing forms of a particularfieldand decide which one to consider. In step 2, I want to take the winners of step 1 for different fields and compare them.

But the scores for each field should be computing using normal scoring? Would this be similar to using thedismaxoredismaxquery parsers? (which creates disjunct queries and uses the max from each sub query as the query's score)
– MatsLindh

Yes each field is scored using normal scoring using any of DisMax or eDisMax parser. I want to create disjunct queries and take max from each subquery more than once.

I fail to see the difference - max(s1, s2) is the same asmax(field1_score, field1_edge_score, field2_score, score_field2_edge_score)which is the same as taking the max from each sub query, isn't it? And "taking the max more than once" would still be the same max, wouldn't it? Can you add examples showing what you want that differs from what the dismax query parsers provide and proper examples of how you'd expect a query to be scored in your example?
