Hi Alvaro,
Could you please point me to some link from where I can see how to index
two documents separately (joined by foreign keys).
Or if you can oblige by putting down some details here itself.
*For example*, say if user has entities like :
car {id:5, color:red, year:2004, companyId:23, ownerId: 57},
company {id:23, name: toyota, numEmployees:1000, established:1980},
owner {id: 57, name: John, age: 50, profession: doctor, spouseId: 78,
carOwnedId: 5},
owner {id: 78, name: Maria, age: 45, profession: doctor, spouseId: 57,
carOwnedId: 55}
etc.
1) How can the above entities be put into Solr with their foreign keys?
2) Do we need to flatten them absolutely?
3) How are cyclic joins handled in flattening?
Some good link on how a join query can be actually run would also be
appreciated.
(I have some links on the reading part, but a complete example would be
good).
Thanks
