-----------------------------------------------------------
[~neerajlajpal] Solr parses the value of q with a single parser, which will be
whatever your defType is. In order to do something like that you can use
nested queries:
{noformat}
important_category:322^4 _query_:{!scorejoin from=_root_ to=id score=avg
multiVals=false v=$jq}&jq=(brandid:1398^4 OR brandid:237^4.5)
{noformat}

> 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.
