-----------------------------------
Summary: GlobalStats, incorrect order of debug results
Key: SOLR-8061
URL: https://issues.apache.org/jira/browse/SOLR-8061
Project: Solr
Issue Type: Bug
Affects Versions: 5.3
Reporter: Markus Jelsma
Fix For: 5.4
It is very tedious to debug the scoring results when GlobalStats is enabled.
Here are the top 5 ID's and their scores:
{code}
<result name="response" numFound="1258" start="0" maxScore="100.59861">
<doc>
<str
name="id">http://www.example.org/medicijnen/paracetamol?product=paracetamol</str>
<float name="score">100.59861</float></doc>
<doc>
<str
name="id">http://www.example.org/medicijnen/paracetamol?product=roter-paracetamol</str>
<float name="score">100.42987</float></doc>
<doc>
<str
name="id">http://www.example.org/medicijnen/paracetamol?product=sinaspril-paracetamol</str>
<float name="score">100.42986</float></doc>
<doc>
<str name="id">http://www.example.org/medicijnen/paracetamol</str>
<float name="score">99.93343</float></doc>
<doc>
<str name="id">http://www.example.org/producten/paracetamolvitamine-c</str>
<float name="score">99.762596</float></doc>
{code}
This is the final debugging information, shortened for readability, full
response attached

...
</str>
{code}
I comparad docId's with a retrieved resultset without GlobalStats, the order of
document ID's is correct, the docId's match. It looks like the debug scores
themselves are incorrect, and thus also wrongly sorted.
