You are talking about "updateDocuments(Term delTerm, Iterable docs)"?
We could add another method with Query like
[https://lucene.apache.org/core/9_6_0/core/org/apache/lucene/index/IndexWriter.html#deleteDocuments(org.apache.lucene.search.Query...)].
Implementation behind could be the same. Basically it would do the same
but just use delQuery using the DocIdSetIteraor of the query and
Iterable for the new block.

Hi folks,
Currently the only way to update a block of documents is by
identifying them with a term and update those documents. However we
have a case where the child documents does not share a same identifier
as parent documents, and to identify the whole block of documents we
need to use at least a disjunction query like: (parentId: xx OR id: xx).
I wonder whether we could add a new API to IndexWriter
supporting that? It seems to me we just need to create a new
DeleteQueue node with queries instead of terms and pass it into
internal updates method? Or am I missing something so that update
using query is not obvious?
Thanks
Patrick
