We use Hybrid search a lot. Great feature!
Can we use multiple keywords when using BM25?
The example provided is only one keyword.

You can put multiple words into the query. As per GraphQL - Vector search parameters | Weaviate - vector database , stop words are removed but the rest are all evaluated. If you add _additional {explainScore} to your query you will see how your different keywords factored into the score.

Simple example:

{
  Get {
    MyClass(
      limit: 30
      bm25: {
        query: "italy life insurance"
      }
    ) {
      text
      _additional
      {
          score
          explainScore
      }
    }
  }
}

Response:

{
    "data": {
        "Get": {
            "MyClass": [
                {
                    "_additional": {
                        "explainScore": ", BM25F_insurance_frequency:11, BM25F_insurance_propLength:161, BM25F_italy_frequency:7, BM25F_italy_propLength:161, BM25F_life_frequency:1, BM25F_life_propLength:161",
                        "score": "4.4186454"
                    }
                }
            ]
        }
    }
}

Note how all the keywords factored into the score.
