Solr debug 'explain' values differ from the Solr score
Hi, I'm seeing behavior in Solr 5.5.0 where the top-level values I see in the debug response don't always correspond with the scores Solr assigns to the matched documents. For example, here is the top-level debug information for two documents matched by a query: 114628: Objectdescription: "sum of:"details: Array[2]match: truevalue: 20.542768 357547: Objectdescription: "sum of:"details: Array[2]match: truevalue: 26.517654 But they have scores114628: 20.542767357547: 13.258826 I expect the second document to be the most relevant for my query, and the debug values seem to agree. However, in the final score I receive, that document's score has been adjusted down. The relevant debug response information can be found here: http://apaste.info/mju Does anyone have an idea why the Solr score may differ from the debug value? Thanks,-Rick
RE: Solr debug 'explain' values differ from the Solr score
After some digging and experimentation, here are some more details on the issue I'm seeing. 1. The adjusted documents' scores are always exactly (debug_score/N), where N is the number of OR items in the query. For example, `&q=firstName:gabby~ firstName_phonetic:gabby firstName_tokens:(gabby)` will result in some of the documents with firstName==GABBY receiving a score 1/3 of the score of other GABBY documents, even though the debug explanation shows that they generated the same score. 2. This doesn't appear to be a brand new issue, or an issue with SolrCloud. I've tested the problem using SolrCloud 5.5.0, Solr 5.5.0 (not cloud), and Solr 5.4.1. Anyone have any ideas?

Try adding the following to your schema just under the tag: This seems to solve the problem for me. Well I at least haven't yet found any cases where I see the score discrepancy.

RE: Explain score is different from score
Yes it seems to be something similar, but the normalization isn't applied to all retrieved documents, which messes with the document rankings. Some documents have the exact values from the 'explain' response, while others are normalized. -Rick > Date: Fri, 18 Mar 2016 16:06:19 + > From: iori...@yahoo.com.INVALID > To: solr-user@lucene.apache.org > Subject: Re: Explain score is different from score > > Hi Rajesh, > > I suspect it is due to the queryNorm(q).

RE: Explain score is different from score
Hi Rajesh, I've been seeing the same problem you have. My debug scores seem to be what I expect, but the actual scores applied by Solr are sometimes divided by an integer. I raised the same question in this email distribution about a week ago, but haven't yet found a solution. There's also a StackOverflow question I created here: http://stackoverflow.com/questions/35921106/how-and-why-do-solr-explain-values-differ-from-the-solr-score Can you verify whether all of your affected scores are (1/N)*score?

RE: Solr debug 'explain' values differ from the Solr score
I still have the problem even without using the phonetic field. For example, the following query will result in some exact name matches having scores of 4.64, while others get 2.32. All debug info has final values of 4.64. &q=( ( (firstName:john~)^0.5 (firstName:john) )^4) I expect all exact matches to score the same, as the debug response seems to indicate they should be. I'm not having success reproducing the issue on a small amount of exported data indexed using post.jar. The issue still appears when I reduced the data pulled by the DIH to only the first 1,000,000 first names, however. Could this be due to some indexing issue with the DIH?

RE: Explain score is different from score
I haven't checked this thread since Friday, but here are my responses to the
questions that have come up.
1. How is ranking affected?
Some documents have their scores divided by an integer value in the response
documents.
2. Do you see the proper ranking in the explain section?
Yes, the explain section always seems to have consistent values and proper
rankings.
3. What about the results?
No, these are ranked according to the sometimes incorrect score.
4. What version of Solr are you using?
I've produced the problem on SolrCloud 5.5.0 (2 shards on 2 nodes on the same
machine), Solr 5.5.0 (no sharding), and Solr 5.4.1 (no sharding).
I've also had trouble reproducing the problem on test data.
Thanks,
-Rick
