Unable to perform knn query [knn] unknown field [k about elasticsearch-net HOT 7 CLOSED

Hello! This is a known issue in the Elasticsearch specification that will be fixed in the next version of the .NET client: elastic/elasticsearch-specification#2490. Sorry about that.

from elasticsearch-net.

As @pquentin said, it's already fixed in the specification. The fix will propagate to the .NET client in the next few days. There is no older version of the 8.* client that correctly supports KNN queries. Hope you don't mind waiting a couple of days 🙂 I'll try to do a patch release already today, but can't promise anything.

Fixed in 8.13.6

@alkampfergit Happy to help you out 🙂 As well thanks to @l-trotta for fixing this issue upstream in the specification.

Is an older version of the driver that works with it? Actually this is pretty a blocking issue in a project of mine because we are planning to use Elastic as vector search.....
