Yonik Seeley commented on SOLR-3076: ------------------------------------ bq. why PARENT:true should ignore deletions? In an earlier iteration, it needed to... but now I think it's just desirable (as opposed to required) because it's more efficient (less backtracking over deleted docs), and more resilient to accidental error conditions (like when someone deletes a parent doc but not it's children). bq. I propose to revise the idea of rewindable docIDset iterator See LUCENE-5092, it looks like something like that has been rejected. As far as maintenance, the current stuff makes some things easier to tweak. I already did so for the child parser to make it fit better with how we put together full queries. Anyway, the important part are the public interfaces (the XML doc, and \{!parent} \{!child} parsers and semantics). If we're happy with those, I think we should commit at this point - this issue has been open for far too long! > Solr(Cloud) should support block joins > -------------------------------------- > > Key: SOLR-3076 > URL: https://issues.apache.org/jira/browse/SOLR-3076 > Project: Solr > Issue Type: New Feature > Reporter: Grant Ingersoll > Assignee: Yonik Seeley > Fix For: 4.5, 5.0 > > Attachments: 27M-singlesegment-histogram.png, 27M-singlesegment.png, > bjq-vs-filters-backward-disi.patch, bjq-vs-filters-illegal-state.patch, > child-bjqparser.patch, dih-3076.patch, dih-config.xml, > parent-bjq-qparser.patch, parent-bjq-qparser.patch, Screen Shot 2012-07-17 at > 1.12.11 AM.png, SOLR-3076-childDocs.patch, SOLR-3076.patch, SOLR-3076.patch, > SOLR-3076.patch, SOLR-3076.patch, SOLR-3076.patch, SOLR-3076.patch, > SOLR-3076.patch, SOLR-3076.patch, SOLR-3076.patch, SOLR-3076.patch, > SOLR-3076.patch, SOLR-3076.patch, SOLR-3076.patch, > SOLR-7036-childDocs-solr-fork-trunk-patched, > solrconf-bjq-erschema-snippet.xml, solrconfig.xml.patch, > tochild-bjq-filtered-search-fix.patch > > > Lucene has the ability to do block joins, we should add it to Solr. -- This message is automatically generated by JIRA.
