Hybrid Retriever for Chroma

[ss2342]

Is there a Hybrid Retriever Implementation of Chroma within Haystack2.0? Or a ChromaB25Retriever that could be then used to construct a hybrid retriever with Chroma? Thanks!

After some investigation, I found that Chroma does not support keyword search.

It only supports filtering the results of embedding retrieval using text. See the docs.

So, if you are interested in true hybrid retrieval, I suggest you take a look at other DBs such as Weaviate, Qdrant, Elasticsearch, OpenSearch...
