Sounds like you are looking for parent/child docs here, see
https://lucene.apache.org/solr/guide/8_5/indexing-nested-documents.html
{
"type": "user",
"name": "user1",
"products": [
{ "id": "prod_A", "cost": 50},
{ "id": "prod_B", "cost": 200},
{ "id": "prod_D", "cost": 25}
]
}
This will index 4 documents - one user document and three product-cost child
documents.
You can then search the child docs and return matching parents with e.g.
q=*:*&fq={!parent which="type:user"}((id:prod_A AND cost:[50 TO 100]) OR
(id:prod_D AND cost:[0 TO 40]))&fl=[child]
Hope this helps.
