Jonathan Rochkind commented on SOLR-2272: ----------------------------------------- This is a feature that would be very useful to me, thus I've had a watch on the ticket. I am not a solr committer and have never even contributed a patch, just a user. But this is a feature I've been wanting for a while, and would be excited to see it in Solr. On the one hand I see the argument that it would ideally go at the lucene layer; on the other hand, if someone has working, tested, well-written code that is is ready at the Solr layer, as a user, I'd really like to see it go in there, to be refactored to lucene at a later date when/if someone else has time/interest -- rather than delaying working code indefinitely for hypothetical future (potentially time-consuming) refactoring at a different layer by yet-to-be-volunteered labor. I put this in only to make clear that there are users in the general population who would like to see this feature get into Solr sooner rather than later, delaying it does matter to 'ordinary' users. (I am neither a Solr contractor nor a customer of a Solr contracter, I don't have any such 'business interests', I am just an in-house developer who writes (open source) software on top of Solr. Not that there's anything wrong with being a Solr contractor, it's a fine way to fund open source development and I think it's odd to imply there's something wrong with it; I'm just saying I'm not one.) Hopefully you committers can work it out amongst yourself in a way that balances the codebase's architectural health with the need to get working code out there. > Join > ---- > > Key: SOLR-2272 > URL: https://issues.apache.org/jira/browse/SOLR-2272 > Project: Solr > Issue Type: New Feature > Components: search > Reporter: Yonik Seeley > Fix For: 4.0 > > Attachments: SOLR-2272.patch, SOLR-2272.patch, SOLR-2272.patch > > > Limited join functionality for Solr, mapping one set of IDs matching a query > to another set of IDs, based on the indexed tokens of the fields. > Example: > fq={!join from=parent_ptr to:parent_id}child_doc:query -- This message is automatically generated by JIRA.
