Solr results relevancy / scoring
I have a situation where.
User search query
q=15%
Solr results contain several documents that are
15%
15%
15%
15%
15 (why?)
15%
15%
I have debugged the query and can see that the score for 15 is higher than
the ones below it.
Why is that? Where can I read in detail about how the scoring is being done?
Thanks

You might paste your URL into http://splainer.io and it will explain your
results ranking to you in a perhaps more helpful way

Yes the term was getting tokenized as 15. And Norms are not ignored.
Thank you for helping understand the issue.

I quote Emir and I would like to ask if the Norms are ignored or not.
If they are not ignored and 15 is one of the search tokens, I can expect an
high score for a doc containing "15" because the Norm value will be quite
high ( as the field contains basically exactly the query term).

To get answer for why 15, you can use field analysis for index/query and
see that "15%" is probably tokenized and as both 15 and 15%.

I'm not sure what the question your asking is. You say
that you have debugged the query and the score for 15 is
higher than the ones below it. What's surprising about that?
Are you saying you don't understand how the score is
calculated? Or the output when adding &debug=true
is inconsistent or what?
Best,
Erick
