We simply index parent and child documents with the same field value,
and group on that, querying both parent and child documents. If you
boost the parent it will show up as the first result in the group. Then
you get all related documents together. in the same group.

Hi,
Thanks for the response, I have considered grouping often, but grouping does
not return the parent document, just the group id. I would still have to add
something to take the group id’s and get the parent documents.
Thanks

Have you considered using grouping? If I understand your requirements, I think
it does what you want.

I will take a look at this. I do have an additional question, since after a
bunch of digging I believe I am going to run into another dead end.
I want to execute the join (or rollup) query, but I want the facets to
represent the facets of all the child documents, not the resulting product
documents. From what I gather, this is not possible.
My thought process of what I want to get goes as follows:
1) Execute my search for children
2) Get the facets for all the children
3) Rollup the child dataset into its parent dataset, keeping the score.
Is this easily possible with the tools available today?
Thanks!

Hello,
AFAIK {!join} doesn't supply any meaningful scores.
I can suggest https://issues.apache.org/jira/browse/SOLR-6234

Hello,
I had sent an email a few days ago talking about implementing a custom
rollup query component. I have changed directions a little bit because I
have learned about the JoinQuery.
I have an index that contains a combination of parent and child documents.
The parent child relationship is always one-to-many.
Here is a very simple sample query:
http://localhost:8983/solr/testcore/select?q=*:*&fq={!join%20from=parent%20to=id}type:child
<http://localhost:8983/solr/testcore/select?q=*:*&fq={!join%20from=parent%20to=id}type:child>
<
http://localhost:8983/solr/testcore/select?q=*:*&fq=%7B!join%20from=parent%20to=id%7Dtype:child
<http://localhost:8983/solr/testcore/select?q=*:*&fq=%7B!join%20from=parent%20to=id%7Dtype:child><http://localhost:8983/solr/testcore/select?q=*:*&fq=%7B!join%20from=parent%20to=id%7Dtype:child
<http://localhost:8983/solr/testcore/select?q=*:*&fq=%7B!join%20from=parent%20to=id%7Dtype:child>>
When I have a more specific query that actually give some meaningful
weights: < q=name:(*Shirt*)%20OR%20name:(*Small*) >, it appears the
rollup query assigns a weight to the parent of the last document
encountered. For example, if a parents 2 children has weights of 1.4 and
0.4 without the join query, the parent has a weight of 0.4 after the join
query.
Is there a way that I can extend or modify the join query so it would
assign the highest child weight to the parent document?
Thanks!!
Darin
