Hoss Man commented on SOLR-3076:
--------------------------------
As i said before...
bq. ...perhaps we should focus on the more user explicit, direct mapping type
QParser type approach Mikhail has already started on for now, and consider that
(_schema driven implicit block joining_) as an enhancement later? (especially
since it's not clear how the indexing side will be managed/enforced...)
what Mikhail's fleshed out here seems like a good starting point for users who
are willing to deal with this at the "low" level (similar in expertness to the
"raw" QParser) , and would be usable *today* for people who take responsibility
of indexing the blocks themselves.
if/when/how we decide to drive the indexing side, we can think about how
if/where/how to automagically hook blockjoin queries into "higher" level
parsers like LuceneQParser, DismaxQueryParser
> Solr should support block joins
