MSSharePointRetriever​

Retrieves content from Microsoft SharePoint and OneDrive via the Microsoft Search (Graph) API.

Given a query, the retriever calls POST /search/query and maps each hit to a Haystack Document whose content is the search snippet and whose meta carries the resource metadata (file_name, web_url, entity_type, created_date_time, last_modified_date_time, created_by, last_modified_by, mime_type, and file_extension). It does not download or convert the underlying files. Compose a downstream fetcher/converter on the returned web_url when full file content is needed.

The retriever takes a per-user access_token as a run input, typically wired from an upstream OAuthResolver. The token must carry delegated Microsoft Graph permissions (for example Files.Read.All and, for site/list scoping, Sites.Read.All). The Search API supports delegated permissions only.

Usage example​

python
from haystack_integrations.components.retrievers.microsoft_sharepoint import (
    MSSharePointRetriever,
)

retriever = MSSharePointRetriever(top_k=5)

# `access_token` is a per-user delegated Microsoft Graph bearer token.
result = retriever.run(
    query="quarterly roadmap", access_token="my-delegated-graph-token"
)
documents = result["documents"]

In a pipeline, connect an upstream component that emits a per-user access_token to the retriever's access_token input. See the integration documentation for a full example that obtains the token from an OAuth provider.

init​

python
__init__(
    *,
    entity_types: list[str] | None = None,
    top_k: int = 10,
    fields: list[str] | None = None,
    query_template: str | None = None,
    graph_url: str = _DEFAULT_GRAPH_URL,
    timeout: float = 30.0,
    max_retries: int = 3
) -> None

Initialize the retriever.

Parameters:

  • entity_types (list[str] | None) – The Microsoft Search entity types to query. Defaults to ["driveItem", "listItem"], which covers files, folders, SharePoint pages and news, and list items. Other valid values are "list" and "site". See the supported values and combinations in the Microsoft docs.
  • top_k (int) – The maximum number of documents to return. Maps to the Search API size and is paginated when it exceeds a single page.
  • fields (list[str] | None) – Optional list of resource properties to request via the Search API fields selection (only honored for listItem and driveItem entity types). See Get selected properties.
  • query_template (str | None) – Optional query template used to scope the search, for example '{searchTerms} path:"https://contoso.sharepoint.com/sites/Team"'. The literal {searchTerms} placeholder is replaced by the run-time query. The template uses Keyword Query Language (KQL).
  • graph_url (str) – The Microsoft Graph base URL. Defaults to https://graph.microsoft.com/v1.0. Override for sovereign clouds.
  • timeout (float) – The HTTP timeout in seconds for each request to Microsoft Graph.
  • max_retries (int) – The maximum number of retries for throttled (HTTP 429) or transient server errors.

Raises:

  • SharePointConfigError – If entity_types is empty, top_k is not positive, or max_retries is negative.

run​

python
run(
    query: str, access_token: str | Secret, top_k: int | None = None
) -> dict[str, list[Document]]

Search SharePoint and OneDrive and return the matching documents.

Parameters:

  • query (str) – The search query string. Filter results by embedding Keyword Query Language (KQL) operators directly in the query, for example filetype:docx, author:"Jane Doe", or path:"https://contoso.sharepoint.com/sites/Team". See the KQL syntax reference.
  • access_token (str | Secret) – A delegated Microsoft Graph bearer token for the user whose content is searched, typically wired from an upstream OAuthResolver (which emits a plain str). A Secret is also accepted and resolved internally.
  • top_k (int | None) – Overrides the top_k configured at initialization for this run.

Returns:

  • dict[str, list[Document]] – A dictionary with a documents key holding the list of retrieved Document objects.

Raises:

  • SharePointConfigError – If access_token is a Secret that does not resolve to a string.
  • SharePointRequestError – If Microsoft Graph returns an error response.

run_async​

python
run_async(
    query: str, access_token: str | Secret, top_k: int | None = None
) -> dict[str, list[Document]]

Asynchronously search SharePoint and OneDrive and return the matching documents.

Parameters:

  • query (str) – The search query string. Filter results by embedding Keyword Query Language (KQL) operators directly in the query, for example filetype:docx, author:"Jane Doe", or path:"https://contoso.sharepoint.com/sites/Team". See the KQL syntax reference.
  • access_token (str | Secret) – A delegated Microsoft Graph bearer token for the user whose content is searched, typically wired from an upstream OAuthResolver (which emits a plain str). A Secret is also accepted and resolved internally.
  • top_k (int | None) – Overrides the top_k configured at initialization for this run.

Returns:

  • dict[str, list[Document]] – A dictionary with a documents key holding the list of retrieved Document objects.

Raises:

  • SharePointConfigError – If access_token is a Secret that does not resolve to a string.
  • SharePointRequestError – If Microsoft Graph returns an error response.

to_dict​

python
to_dict() -> dict[str, Any]

Serialize this component to a dictionary.

Returns:

  • dict[str, Any] – The serialized component as a dictionary.

from_dict​

python
from_dict(data: dict[str, Any]) -> MSSharePointRetriever

Deserialize this component from a dictionary.

Parameters:

  • data (dict[str, Any]) – The dictionary representation of this component.

Returns:

  • MSSharePointRetriever – The deserialized component instance.
