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
