+
+### SerperDevWebSearch
+
+Uses [Serper](https://serper.dev/) to search the web for relevant documents.
+
+See the [Serper Dev website](https://serper.dev/) for more details.
+
+Usage example:
+
+```python
+from haystack.utils import Secret
+
+from haystack_integrations.components.websearch.serperdev import SerperDevWebSearch
+
+serper_dev_api = Secret.from_env_var("SERPERDEV_API_KEY")
+
+websearch = SerperDevWebSearch(top_k=10, api_key=serper_dev_api)
+results = websearch.run(query="Who is the boyfriend of Olivia Wilde?")
+
+assert results["documents"]
+assert results["links"]
+
+# Example with domain filtering - exclude subdomains
+websearch_filtered = SerperDevWebSearch(
+    top_k=10,
+    allowed_domains=["example.com"],
+    exclude_subdomains=True,  # Only results from example.com, not blog.example.com
+    api_key=serper_dev_api,
+)
+results_filtered = websearch_filtered.run(query="search query")
+```
+
+#### __init__
+
+```python
+__init__(
+    api_key: Secret = Secret.from_env_var("SERPERDEV_API_KEY"),
+    top_k: int | None = 10,
+    allowed_domains: list[str] | None = None,
+    search_params: dict[str, Any] | None = None,
+    *,
+    exclude_subdomains: bool = False
+) -> None
+```
+
+Initialize the SerperDevWebSearch component.
+
+**Parameters:**
+
+- **api_key** (<code>Secret</code>) – API key for the Serper API.
+- **top_k** (<code>int | None</code>) – Number of documents to return.
+- **allowed_domains** (<code>list\[str\] | None</code>) – List of domains to limit the search to.
+- **exclude_subdomains** (<code>bool</code>) – Whether to exclude subdomains when filtering by allowed_domains.
+  If True, only results from the exact domains in allowed_domains will be returned.
+  If False, results from subdomains will also be included. Defaults to False.
+- **search_params** (<code>dict\[str, Any\] | None</code>) – Additional parameters passed to the Serper API.
+  For example, you can set 'num' to 20 to increase the number of search results.
+  See the [Serper website](https://serper.dev/) for more details.
+
+#### to_dict
+
+```python
+to_dict() -> dict[str, Any]
+```
+
+Serializes the component to a dictionary.
+
+**Returns:**
+
+- <code>dict\[str, Any\]</code> – Dictionary with serialized data.
+
+#### from_dict
+
+```python
+from_dict(data: dict[str, Any]) -> SerperDevWebSearch
+```
+
+Deserializes the component from a dictionary.
+
+**Parameters:**
+
+- **data** (<code>dict\[str, Any\]</code>) – The dictionary to deserialize from.
+
+**Returns:**
+
+- <code>SerperDevWebSearch</code> – The deserialized component.
+
+#### run
+
+```python
+run(query: str) -> dict[str, list[Document] | list[str]]
+```
+
+Use [Serper](https://serper.dev/) to search the web.
+
+**Parameters:**
+
+- **query** (<code>str</code>) – Search query.
+
+**Returns:**
+
+- <code>dict\[str, list\[Document\] | list\[str\]\]</code> – A dictionary with the following keys:
+- "documents": List of documents returned by the search engine.
+- "links": List of links returned by the search engine.
+
+**Raises:**
+
+- <code>SerperDevError</code> – If an error occurs while querying the SerperDev API.
+- <code>TimeoutError</code> – If the request to the SerperDev API times out.
+
+#### run_async
+
+```python
+run_async(query: str) -> dict[str, list[Document] | list[str]]
+```
+
+Asynchronously uses [Serper](https://serper.dev/) to search the web.
+
+This is the asynchronous version of the `run` method with the same parameters and return values.
+
+**Parameters:**
+
+- **query** (<code>str</code>) – Search query.
+
+**Returns:**
+
+- <code>dict\[str, list\[Document\] | list\[str\]\]</code> – A dictionary with the following keys:
+- "documents": List of documents returned by the search engine.
+- "links": List of links returned by the search engine.
+
+**Raises:**
+
+- <code>SerperDevError</code> – If an error occurs while querying the SerperDev API.
+- <code>TimeoutError</code> – If the request to the SerperDev API times out.
