Hello, This is the first time I reach out in this forum, so I apologize in advance if this is a known issue or if I have not spent enough time reading carefully through previous posts.
I am working with a solr containing library data. We have a nested structure where a "work" can have child documents that represent different "pids" (or manifestations) for that work. The canonical example is the work "Harry Potter and the Philosopher's Stone" that can have different manifestations/pids representing for example an audiobook version, an e-book version, and of course, the physical book. Some information, like the title and the author is stored at the work level, and other information, like the materialType (book/audiobook/ebook) or the year is stored at the manifestation/pid level in child docs. I hope that makes sense. It is of course simplified, but it should convey what we are trying to do. I can provide the full schema of our solr if necessary, but there's a lot of info in there that I am not sure would convey much information. If need be, I will be happy to provide it, though. But I thought I'd try and describe a simplified version of the issue I am struggling with. There's a Danish author called Hans Scherfig and I want to search for physical books by him. I issue this query to our solr. As you can see, I have enabled debugging at the `query` level. ```json { "query": "(scherfig)+{!parent which='doc_type:work' v='pid.material_type:(\"bog\")'}", "filter": [ "doc_type:work" ], "fields": "work.workid work.title, [child childFilter='pid.material_type:(\"bog\")']", "offset": 0, "limit": 1, "params": { "defType": "edismax", "qf": [ "work.creator", "work.title", "pid.material_type" ], "pf": "work.creator", "sort": "score desc", "debug": "query" } } ``` We send this to the /query endpoint of solr, like this (the core is called simple-search): ``` curl -H "Content-Type: application/json" "http://search-solr/solr/simple-search/query" -d @scherfig-filter-test.json ``` I am using the `parent which` construction, documented here, for example: https://solr.apache.org/guide/8_2/other-parsers.html (we are on solr 8.10.1). Looking at the debug output, I see this: ``` (work.creator:\"scherfig parent which doc_type:work v pid.material_type\") ``` which worries me slightly. It looks like "parent which" is part of what solr is looking for in the work.creator field? The "interesting" bit is that, if I remove the line with `"pf":"work.creator"`, then that part of the debug output is no longer there. Is there an issue with `pf` here? Or am I formatting my query wrongly? Thanks in advance for any insight you can provide. Best regards, /Noah -- Noah Torp-Smith (n...@dbc.dk)
