semantic score not generated when sending a query using vectorstore.similarity_search method

[AhmedMostafa08]

Description
when trying to send a query using vectorstore.similarity_search i get a KeyError: '_semanticScore' as the result doesn't have a semantic score generated
semantic_score = result["_semanticScore"]

Expected behavior
to get a response

Current behavior
the mentioned error happens

here's the code for how I created the vector index :
client=meilisearch.Client('url','api key ')
embeddings = OpenAIEmbeddings()
vectorstore = Meilisearch(
embedding=embeddings,
client=client,
embedders=embedders,
index_name='vector_index')
and here's the embedding and embedder code
embeddings = OpenAIEmbeddings()
embedders = {
"default": {
"source": "userProvided",
"dimensions": 1536,
}
}
embedder_name = "default"

also note that the vector store is created and documents are added just fine
and here's an example for the indexed document
