Is there any documentation on the support (or lack thereof) for using join,
hashJoin and other operations to combine streams on multiValued fields?
I have a core with posts that can be written about multiple companies, and
another core with info about those companies:
{
'id': 'post-1234',
'body': 'the body text about IBM and Oracle',
'company_ids': [21, 43]
}
{
'id': 'company-21',
'company_id': 21,
'name': 'IBM',
}
{
'id': 'company-43',
'company_id': 43,
'name': 'Oracle'
}
I want to join posts to companies.
As an aside, this might not be possible yet before SOLR-8395 is completed
(query-time join (with scoring) for single value numeric fields) but I
thought I'd ask about multiValued fields anyway.
