If I understand correctly, I believe you would want to use a TermInSetQuery query. An example usage can be found here https://github.com/zuliaio/zuliasearch/blob/main/zulia-server/src/main/java/io/zulia/server/index/ZuliaIndex.java#L398.
You can also check out the usage of KnnVectorQuery here: https://github.com/zuliaio/zuliasearch/blob/main/zulia-server/src/main/java/io/zulia/server/index/ZuliaIndex.java#L419 noting that in this case the getPreFilter method a few lines below uses 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. ~Matt On Wed, Aug 31, 2022 at 11:15 AM Michael Wechner <michael.wech...@wyona.com> wrote: > 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 and use as filter, just as I use > TermQuery as filter above? > > Thanks > > Michael >
