As a user I want to use FAISS's HNSW for cosine similarity too with `OpenSearchDocumentStore`. According to https://opensearch.org/docs/latest/search-plugins/knn/knn-index/ FAISS plug-in only supports dot product and l2. So we have to...

**Describe the bug** Setting optional params to `null` in YAML (or to `None` when it's been converted to a python dict) will cause the schema validation to fail: see https://github.com/deepset-ai/haystack/issues/2586...

Introduce `RetrievalModel` abstract base class

1

**Proposed Changes:** - add `RetrievalModel` ABC - make `SparseSearch`, `BM25Search`, `DenseRetrievalFaissSearch` and `DenseRetrievalExactSearch` inherit from `RetrievalModel` - `EvaluateRetrieval` receives `RetrievalModel` as param - rename `retriever` to `retrieval_model` in `EvaluateRetrieval` -...

Support for custom retrievers: common base type for `EvaluateRetrieval`'s `retriever` param

3

The current design of `EvaluateRetrieval` is already supporting multiple different retrievers. See https://github.com/beir-cellar/beir/blob/bb8a0582d8a82d6f4fddee8b668b1ebaa42985ef/beir/retrieval/evaluation.py#L14 However according to typings the supplied retrievers are limited to those implemented in BEIR. If we want...
