LocalIndex Objects

class LocalIndex(BaseIndex)

add

def add(embeddings: List[List[float]],
        routes: List[str],
        utterances: List[str],
        function_schemas: Optional[List[Dict[str, Any]]] = None,
        metadata_list: List[Dict[str, Any]] = [],
        **kwargs)

Add embeddings to the index.

Arguments:

embeddings (List[List[float]]): List of embeddings to add to the index.
routes (List[str]): List of routes to add to the index.
utterances (List[str]): List of utterances to add to the index.
function_schemas (Optional[List[Dict[str, Any]]]): List of function schemas to add to the index.
metadata_list (List[Dict[str, Any]]): List of metadata to add to the index.

get_utterances

def get_utterances(include_metadata: bool = False) -> List[Utterance]

Gets a list of route and utterance objects currently stored in the index.

Arguments:

include_metadata: Whether to include function schemas and metadata in the returned Utterance objects - LocalIndex now includes metadata if present.

Returns:

List[Utterance]: A list of Utterance objects.

describe

def describe() -> IndexConfig

Describe the index.

Returns:

IndexConfig: An IndexConfig object.

is_ready

def is_ready() -> bool

Checks if the index is ready to be used.

Returns:

bool: True if the index is ready, False otherwise.

ais_ready

async def ais_ready() -> bool

Checks if the index is ready to be used asynchronously.

Returns:

bool: True if the index is ready, False otherwise.

query

def query(
    vector: np.ndarray,
    top_k: int = 5,
    route_filter: Optional[List[str]] = None,
    sparse_vector: dict[int, float] | SparseEmbedding | None = None
) -> Tuple[np.ndarray, List[str]]

Search the index for the query and return top_k results.

Arguments:

vector (np.ndarray): The vector to search for.
top_k (int): The number of results to return.
route_filter (Optional[List[str]]): The routes to filter the search by.
sparse_vector (dict[int, float] | SparseEmbedding | None): The sparse vector to search for.

Returns:

Tuple[np.ndarray, List[str]]: A tuple containing the query vector and a list of route names.

aquery

async def aquery(
    vector: np.ndarray,
    top_k: int = 5,
    route_filter: Optional[List[str]] = None,
    sparse_vector: dict[int, float] | SparseEmbedding | None = None
) -> Tuple[np.ndarray, List[str]]

Search the index for the query and return top_k results.

Arguments:

vector (np.ndarray): The vector to search for.
top_k (int): The number of results to return.
route_filter (Optional[List[str]]): The routes to filter the search by.
sparse_vector (dict[int, float] | SparseEmbedding | None): The sparse vector to search for.

Returns:

Tuple[np.ndarray, List[str]]: A tuple containing the query vector and a list of route names.

aget_routes

async def aget_routes()

Get all routes from the index.

Returns:

List[str]: A list of routes.

delete

def delete(route_name: str)

Delete all records of a specific route from the index.

Arguments:

route_name (str): The name of the route to delete.

adelete

async def adelete(route_name: str)

Delete all records of a specific route from the index. Note that this just points

to the sync delete method as async makes no difference for the local computations of the LocalIndex.

Arguments:

route_name (str): The name of the route to delete.

delete_index

def delete_index()

Deletes the index, effectively clearing it and setting it to None.

Returns:

None: None

adelete_index

async def adelete_index()

Deletes the index, effectively clearing it and setting it to None. Note that this just points

to the sync delete_index method as async makes no difference for the local computations of the LocalIndex.

Returns:

None: None
