Rounding errors with SOLR score
When doing complex boosting/bq we are getting rounding errors on the score.
To get the score to be consistent I needed to use rint on sort:
sort=rint(product(sum($p_score,$s_score,$q_score),100)) desc,s_query asc
<str name="p_score">recip(priority,1,.5,.01)</str>
<str name="s_score">product(recip(synonym_rank,1,1,.01),17)</str>
<str name="q_score">
query({!dismax qf="user_query_edge^1 user_query^0.5 user_query_fuzzy"
v=$q1})
</str>
The issue is in the qf area.
{"s_query": "Ear Irrigation","score": 10.331313},{"s_query": "Ear Piercing",
"score": 10.331314},{"s_query": "Ear Pinning","score": 10.331313},

I will send the debugQuery. They are exactly the same.

Are you sure that SOLR is rounding incorrectly, and not simply differently
from what you expect? I was surprised myself at some of the rounding
behaviour I saw with SOLR, but according to
http://en.wikipedia.org/wiki/Rounding , the results were valid (just not
the round-up-from-half that I naively expected).
