Create a Clarifai vectorstore from a list of texts.
Parameters
user_id (str) – User ID.
app_id (str) – App ID.
texts (List[str]) – List of texts to add.
number_of_docs (Optional[int]) – Number of documents to return
None. (Defaults to) – 
metadatas (Optional[List[dict]]) – Optional list of metadatas.
None. – 
Returns

Return type
Clarifai
max_marginal_relevance_search(query: str, k: int = 4, fetch_k: int = 20, lambda_mult: float = 0.5, **kwargs: Any) → List[Document]¶
Return docs selected using the maximal marginal relevance.
Maximal marginal relevance optimizes for similarity to query AND diversity
among selected documents.
Parameters
query – Text to look up documents similar to.
k – Number of Documents to return. Defaults to 4.
fetch_k – Number of Documents to fetch to pass to MMR algorithm.
lambda_mult – Number between 0 and 1 that determines the degree
of diversity among the results with 0 corresponding
to maximum diversity and 1 to minimum diversity.
Defaults to 0.5.
Returns
