Thanks! I am aware of the examples in the docs but they don't quite answer my
specific question about parent/child joins on multiple levels in a general way.
Here is a slightly modified example that actually works on ElasticSearch with
an equivalent (nested) schema. I can't figure out how to exp
Hello Alain,
If I was going to implement queries on deeply nested documents, I can see
quite a few examples here :
https://solr.apache.org/guide/8_8/searching-nested-documents.html#parent-query-parser
In a hierarchy like below the following query with a criteria on
_nest_path_ suppose to retriev
Did you try routing all docs for the same customer ID to the same
shard (not block join), just docs of different types in the same shard
based on customer ID and then using Joins?

Thanks, but as far as I understand this is "just" a different, Json-based
syntax for the same underlying feature (join queries, no support for
parent/child block joins). So alas! my questions remain open. I have been
unable so far to find any comprehensive example I could relate to, and I have
Thanks, Tim. Alas, this is nothing more than a join query in Json syntax, so
does not really explain how the sort of query I am looking for could be
expressed. Any takers ?

Might take a look at the domain join stuff in JSON facets too:

Hi,
Thanks, I knew about that one, but note the date : 2012. A lot has changed in
the meantime, specifically block joins and improved nested documents support.
But I wonder about what can be expressed, even if we leave performance issues
aside for another post. I can't find a comprehensive exam

Hi,
Imagine that you have been tasked with designing a Solr-based system that
indexes and queries data aggregated from several relational databases. All the
data items are ultimately related to a common object type, so the logical data
schema looks like :
Customer
Profile
Events
10 matches
Mail list logo
