Is there a way to query documents that aren’t referenced by another type of document? I’m trying to delete documents that aren’t being referenced.

Found the solution from an old script I think

had sent me to remove assets that were not being used. No idea how this query works or what it is doing but it brings me back the IDs I want to delete.

ah that's handy thanks, a quick explication how it works
1. fetch all documents of type offer

*[_type in ["offer"]]
2. include _id and and refs (refs containing count of references)

"refs": count(*[ references(^._id) ])
3. filter results to only show data where refs count == 0 and then return only the id

[ refs == 0 ]._id

*[ _type in ["offer"]]{
  "refs": count(*[references(^._id)])
}[refs == 0]._id
