Neeraj Lajpal commented on SOLR-6234:
-------------------------------------
Thanks a lot Ryan.
This solved my problem.
But, needed to change a couple of things, enclose the value of _query_ in
double quotes and remove jq.
Without these changes it was not showing any result.
I executed this query:
important_category:322^4 _query_:"{!scorejoin from=_root_ to=id score=avg
multiVals=false}(brandid:1398^4 OR brandid:237^4.5)"
"debug": {
"rawquerystring": "important_cat:322^4 _query_:\"{!scorejoin from=_root_
to=id score=avg multiVals=false}(brandid:1398^4 OR brandid:237^4.5)\"",
"querystring": "important_cat:322^4 _query_:\"{!scorejoin from=_root_ to=id
score=avg multiVals=false}(brandid:1398^4 OR brandid:237^4.5)\"",
"parsedquery": "important_cat:322^4.0 SameCoreJoinQuery(SameCoreJoinQuery
[fromQuery=brandid:1398^4.0 brandid:237^4.5, fromField=_root_, toField=id,
scoreMode=Avg, boost=1.0, multiVals=false])"
}
Everything looks fine.
Thanks again.

> it adds {{scorejoin}} query parser which calls Lucene's JoinUtil underneath.
> It supports:
> - {{score=none|avg|max|total}} local param (passed as ScoreMode to JoinUtil)
> - {{score=none}} is *default*, eg if you *omit* this localparam
> - supports {{b=100}} param to pass {{Query.setBoost()}}.
> - {{multiVals=true|false}} is introduced
> - there is a test coverage for cross core join case.
> - so far it joins string and multivalue string fields (Sorted, SortedSet,
> Binary), but not Numerics DVs. follow-up LUCENE-5868
> -there was a bug in cross core join, however there is a workaround for it-
> it's fixed in Dec'14 patch.
