Christine Poerschke commented on SOLR-12235:
--------------------------------------------
Thanks [~bogdanstoik] and [~stefan.langenmaier] for reporting this issue here
and in SOLR-12323 with how-to-reproduce steps.
I've done a quick scan through {{solr/CHANGES.txt}} and nothing jumped out to
me as obvious point to start looking into.
Slightly more systematically, a next investigative step could be to build a
small exploratory test case - e.g. based upon
https://github.com/apache/lucene-solr/blob/master/solr/core/src/test/org/apache/solr/HelloWorldSolrCloudTestCase.java
- which passes at
https://github.com/apache/lucene-solr/tree/releases/lucene-solr/7.2.1 commit
point but fails on
https://github.com/apache/lucene-solr/tree/releases/lucene-solr/7.3.0 commit
point and then to 'zoom in' towards the unknown commit point(s) in between at
which the info went missing.
> Incomplete debugQuery info when using edismax and boost param
> -------------------------------------------------------------

> Key: SOLR-12235
> URL: https://issues.apache.org/jira/browse/SOLR-12235
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: query parsers, search
> Affects Versions: 7.3
> Environment: Solr 7.3.0, Java 1.8.0_162
> Reporter: Bogdan Stoica
> Priority: Minor
>
> There is an issue with the way SOLR 7.3 outputs explain information when
> using edismax and
> boost param.
>
> Example query:
> /select?boost=results&debugQuery=on&defType=edismax&q=word&qf=text
>
> Solr 7.3 outputs:
>
> {code:java}
> <str name="word">
> 31349.63 = product of: 1.0 = boost 31349.63 = boost(double(results))
> </str>{code}
>
>
> In comparrison, Solr 7.2.1 returns the following:
>
> {code:java}
> <str name="word">
> 31349.63 = boost(text:word,double(results)), product of: 14.400382 =
> weight(text:word in 18142) [SchemaSimilarity], result of: 14.400382 =
> score(doc=18142,freq=1.0 = termFreq=1.0 ), product of: 10.677335 = idf,
> computed as log(1 + (docCount - docFreq + 0.5) / (docFreq + 0.5)) from: 6.0 =
> docFreq 281851.0 = docCount 1.3486869 = tfNorm, computed as (freq * (k1 + 1))
> / (freq + k1 * (1 - b + b * fieldLength / avgFieldLength)) from: 1.0 =
> termFreq=1.0 1.2 = parameter k1 0.75 = parameter b 2.7172585 = avgFieldLength
> 1.0 = fieldLength 2177.0 = double(results)=2177.0
> </str>{code}
