David Smiley resolved SOLR-6096. -------------------------------- Resolution: Duplicate Fix Version/s: 8.0 I'm closing this as a Duplicate, of multiple issues that basically fixed this for 8.0. Not everything is perfect... in particular one has to be careful with delete-by-query but that's at least documented now. That will be difficult to address. > Support Update and Delete on nested documents > --------------------------------------------- > > Key: SOLR-6096 > URL: https://issues.apache.org/jira/browse/SOLR-6096 > Project: Solr > Issue Type: Improvement > Affects Versions: 4.7.2 > Reporter: Thomas Scheffler > Priority: Major > Labels: blockjoin, nested > Fix For: 8.0 > > > When using nested or child document. Update and delete operation on the root > document should also affect the nested documents, as no child can exist > without its parent :-) > Example > {code:xml|title=First Import} > <doc> > <field name="id">1</field> > <field name="title">Article with author</field> > <doc> > <field name="name">Smith, John</field> > <field name="role">author</field> > </doc> > </doc> > {code} > If I change my mind and the author was not named *John* but *_Jane_*: > {code:xml|title=Changed name of author of '1'} > <doc> > <field name="id">1</field> > <field name="title">Article with author</field> > <doc> > <field name="name">Smith, Jane</field> > <field name="role">author</field> > </doc> > </doc> > {code} > I would expect that John is not in the index anymore. Currently he is. There > might also be the case that any subdocument is removed by an update: > {code:xml|title=Remove author} > <doc> > <field name="id">1</field> > <field name="title">Article without author</field> > </doc> > {code} > This should affect a delete on all nested documents, too. The same way all > nested documents should be deleted if I delete the root document: > {code:xml|title=Deletion of '1'} > <delete> > <id>1</id> > <!-- implying also > <query>_root_:1</query> > --> > </delete> > {code} > This is currently possible to do all this stuff on client side by issuing > additional request to delete document before every update. It would be more > efficient if this could be handled on SOLR side. One would benefit on atomic > update. The biggest plus shows when using "delete-by-query". > {code:xml|title=Deletion of '1' by query} > <delete> > <query>title:*</query> > <!-- implying also > <query>_root_:1</query> > --> > </delete> > {code} > In that case one would not have to first query all documents and issue > deletes by those id and every document that are nested. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
