DDGSWebSearch​

Searches the web with ddgs (Dux Distributed Global Search) and returns results as Haystack Documents.

ddgs is a free, keyless metasearch library that aggregates results from multiple backends (DuckDuckGo, Google, Bing, Brave, Yahoo, Yandex, Mullvad, and more), so no API key is required.

Usage example​

python
from haystack_integrations.components.websearch.ddgs import DDGSWebSearch

websearch = DDGSWebSearch(top_k=5)
result = websearch.run(query="What is Haystack by deepset?")

documents = result["documents"]
links = result["links"]

init​

python
__init__(
    top_k: int = 10,
    backend: str = "auto",
    region: str = "us-en",
    safesearch: str = "moderate",
    search_params: dict[str, Any] | None = None,
) -> None

Initialize the DDGSWebSearch component.

Parameters:

  • top_k (int) – Maximum number of results to return.
  • backend (str) – Comma-separated ddgs backends to query, or "auto" to let ddgs choose (for example "duckduckgo, google, brave"). See the ddgs docs for the full list.
  • region (str) – Region/locale for the search, for example "us-en", "de-de", or "wt-wt" (no region).
  • safesearch (str) – Safe-search level: "on", "moderate", or "off".
  • search_params (dict[str, Any] | None) – Additional keyword arguments forwarded to DDGS().text() (for example page or timelimit). Values here override backend, region, safesearch, and top_k on conflict.

warm_up​

python
warm_up() -> None

Initialize the ddgs client.

Called automatically on first use. Can be called explicitly to avoid cold-start latency.

run​

python
run(query: str) -> dict[str, list[Document] | list[str]]

Use ddgs to search the web.

Parameters:

  • query (str) – Search query.

Returns:

  • dict[str, list[Document] | list[str]] – A dictionary with the following keys:
  • documents: List of documents returned by the search backends.
  • links: List of links returned by the search backends.

run_async​

python
run_async(query: str) -> dict[str, list[Document] | list[str]]

Asynchronously use ddgs to search the web.

ddgs has no native async API, so the blocking search runs in a worker thread. Same parameters and return values as :meth:run.

Parameters:

  • query (str) – Search query.

Returns:

  • dict[str, list[Document] | list[str]] – A dictionary with documents and links keys.
