Hi Julie
Cool, thanks!
I try to apply it and if it works could create an example to the demo
package.
Will keep you posted :-)
Thanks

Hello Michael, we don't yet have an example of kNN with filtering in the
demo package. This would be nice to add!
For now maybe looking at the unit tests could give a sense of how to use
it. Here's an example:
https://github.com/apache/lucene/blob/main/lucene/core/src/test/org/apache/lucene/search/TestKnnVectorQuery.java#L115-L127.
The idea is that KnnVectorQuery optionally accepts a Query as a filter, and
returns the k nearest vectors that also match the filter. Many people refer
to this as "kNN with prefiltering" (as opposed to "postfiltering", where
the filter is applied *after* the kNN search, so in the end you may receive
fewer than k matches).
Let us know if you run into any questions/ issues while trying it out!

Hi
I noticed that Lucene 9.1.0 supports filtering in nearest-neighbor
vector search, which is great :-)

but it is not really clear to me how to use it.
Is there some additional documentation / example / demo how I can
combine filtering with vector search?
Thanks
