Hi
I am currently filtering a KnnVectorQuery as follows
Query filter =new TermQuery(new Term(CLASSIFICATION_FIELD, classification));
query =new KnnVectorQuery(VECTOR_FIELD, queryVector, k, filter);
but it is not clear to me how I can filter for multiple terms.
Should I subclass MultiTermQuery
a
BooleanQuery.Builder.
As noted in TermsInSetQuery (
https://github.com/apache/lucene/blob/main/lucene/core/src/java/org/apache/lucene/search/TermInSetQuery.java#L62)
multiple terms could be represented as a boolean query with Occur.SHOULD.

I would guess that you are configuring your IndexWriterConfig with a

What is your take on "comparing Lucene and Vespa re HSWN latency and
recall"?

is a compromise. We've known for centuries that "Odyous of olde been

I am using Lucen 9.4.2 vector search and everything seems to work fine,
except that when I delete some documents from the index, then the method
