-----------------------------------

             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

{code}
<lst name="explain">

), product of:

    17.886435 = score(doc=45385,freq=5.0 = termFreq=5.0
...
</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.
