Hi,
Having a question on join score, why doesn't the solr join query return
the scores. Looking at the code, I see there's JoinScorer defined in
the JoinQParserPlugin class ? If its not used for scoring ? where is it
actually used.
Also, to evaluate the performance of solr join plugin vs lucene
joinutil, I filed same join query against same data-set and same schema
and in the results, I am always seeing the Qtime for Solr much lower
then lucenes. What is the reason behind this ? Solr doesn't return
scores could that cause so much difference ?
My guess is solr has very sophisticated caching mechanism and that might
be coming in play, is that true ? or there's difference in the way JOIN
happens in the 2 approach.
If I understand correctly both the implementation are using 2 pass
approach - first all the terms from fromField and then returns all
documents that have matching terms in a toField
If somebody can throw some light, would highly appreciate.
Thanks,
Anand
