Return VectorStore initialized from documents and embeddings.
classmethod from_params(embedding: Embeddings, work_dir: str, n_dim: int, dist_metric: Literal['cosine', 'ip', 'l2'] = 'cosine', max_elements: int = 1024, index: bool = True, ef_construction: int = 200, ef: int = 10, M: int = 16, allow_replace_deleted: bool = True, num_threads: int = 1, **kwargs: Any) → DocArrayHnswSearch[source]¶
Initialize DocArrayHnswSearch store.
Parameters
embedding (Embeddings) – Embedding function.
work_dir (str) – path to the location where all the data will be stored.
n_dim (int) – dimension of an embedding.
dist_metric (str) – Distance metric for DocArrayHnswSearch can be one of:
“cosine”, “ip”, and “l2”. Defaults to “cosine”.
max_elements (int) – Maximum number of vectors that can be stored.
Defaults to 1024.
index (bool) – Whether an index should be built for this field.
Defaults to True.
ef_construction (int) – defines a construction time/accuracy trade-off.
Defaults to 200.
ef (int) – parameter controlling query time/accuracy trade-off.
Defaults to 10.
M (int) – parameter that defines the maximum number of outgoing
connections in the graph. Defaults to 16.
allow_replace_deleted (bool) – Enables replacing of deleted elements
with new added ones. Defaults to True.
num_threads (int) – Sets the number of cpu threads to use. Defaults to 1.
**kwargs – Other keyword arguments to be passed to the get_doc_cls method.
