What/Why

What are you proposing?

OpenSearch supports Hybrid Query since 2.10 however, using OpenSearch.NET client query DSL we cannot create Hybrid Query today.

Thanks for the report @venkateshmunnuri, we have a couple other related open issues regarding neural search & search pipelines (#372 & #451). If anyone is willing to contribute a PR toward any of this work it'd be greatly appreciated. In the meantime it is possible to make these requests using the "raw" HTTP methods of the client, an example of doing this for the neural query type can be seen here: https://github.com/opensearch-project/opensearch-net/blob/main/samples/Samples/NeuralSearch/NeuralSearchSample.cs#L175-L195
