I see nothing in the documentation suggesting a query with a join filter doesn't work when a single collection is involved. There is the special deployment instructions when joining across two distinct collections, but this is not my case.
I have a single collection: I have two VM's, both running Solrcloud. My collection has 2 shards on two different nodes. Max shards per node is set to 1 and replication factor is set to 1. The join filter is: {!join from=expctr-label-memberIds to=expctr-id}expctr-id:4b6f7d34-a58b-3399-b077-685951d06738 When I run the query, I get back only the document with expctr-id: 2087d22a-6157-306f-8386-8352e7d8e4d4 This looks, maybe, like it only finds a document on the replica handling the query. Shouldn't it search and filter across the entire collection? The documents: { "expctr-name":"online account opening", "expctr-description":["Journey for online customers"], "expctr-created":1536947719132, "expctr-to-date":1546232400000, "expctr-from-date":1538366400000, "expctr-id":"89ec679b-24df-3559-8428-124640c96230", "expctr-creator":"SP", "expctr-type":"journey", "_version_":1611606406752894976}, { "expctr-name":"drop-in account opening", "expctr-description":["Journey for dropin customers"], "expctr-created":1536947827643, "expctr-to-date":1546232400000, "expctr-from-date":1538366400000, "expctr-id":"2087d22a-6157-306f-8386-8352e7d8e4d4", "expctr-creator":"SP", "expctr-type":"journey", "_version_":1611606520475156480}, { "expctr-name":"placeholder", "expctr-label":"customers", "expctr-created":1536947679984, "expctr-to-date":0, "expctr-from-date":0, "expctr-id":"4b6f7d34-a58b-3399-b077-685951d06738", "expctr-creator":"SP", "expctr-type":"label", "expctr-label-memberIds":["89ec679b-24df-3559-8428-124640c96230", "2087d22a-6157-306f-8386-8352e7d8e4d4"], "_version_":1611606544788488192}] }
