### Description
There have been multiple discussions around supporting higher vector quantization levels (e.g. more than scalar quantization can provide).
We (elastic) have been doing some researc…

# Summary
While testing post-filtering that I implemented with Faiss in C++, I encountered an issue where the KNN search does not return the expected neighbors connected in the graph, even thou…

Using the example from #277, one can observe that the performance of the fused distance+knn kernels are not ideal when the number of queries is low. The task is:
- tune the configuration of the fused…

### Description
Following the vector search demo in `/app/enterprise_search/vector_search` I wanted to see the equation that is used to generate the score, in a similar way to lexical search with BM2…

### Feature Description
Currently, when `OpensearchVectorClient` class is being created, it checks for the requested index to exist, and creates it, if it does not.
It is implemented [here](https:…
