How to filter KnnVectorQuery with multiple terms?

[Michael Wechner]

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
