## haystack_integrations.components.websearch.searchapi.websearch

### SearchApiWebSearch

Uses [SearchApi](https://www.searchapi.io/) to search the web for relevant documents.

Usage example:

```python
from haystack.utils import Secret

from haystack_integrations.components.websearch.searchapi import SearchApiWebSearch

websearch = SearchApiWebSearch(top_k=10, api_key=Secret.from_env_var("SEARCHAPI_API_KEY"))
results = websearch.run(query="Who is the boyfriend of Olivia Wilde?")

assert results["documents"]
assert results["links"]
```

#### __init__

```python
__init__(
    api_key: Secret = Secret.from_env_var("SEARCHAPI_API_KEY"),
    top_k: int | None = 10,
    allowed_domains: list[str] | None = None,
    search_params: dict[str, Any] | None = None,
) -> None
```

Initialize the SearchApiWebSearch component.

**Parameters:**

- **api_key** (<code>Secret</code>) – API key for the SearchApi 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.
- **search_params** (<code>dict\[str, Any\] | None</code>) – Additional parameters passed to the SearchApi API.
  For example, you can set 'num' to 100 to increase the number of search results.
  See the [SearchApi website](https://www.searchapi.io/) for more details.

The default search engine is Google, however, users can change it by setting the `engine`
parameter in the `search_params`.

#### 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]) -> SearchApiWebSearch
```

Deserializes the component from a dictionary.

**Parameters:**

- **data** (<code>dict\[str, Any\]</code>) – The dictionary to deserialize from.

**Returns:**

- <code>SearchApiWebSearch</code> – The deserialized component.

#### run

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

Uses [SearchApi](https://www.searchapi.io/) 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>TimeoutError</code> – If the request to the SearchApi API times out.
- <code>SearchApiError</code> – If an error occurs while querying the SearchApi API.

#### run_async

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

Asynchronously uses [SearchApi](https://www.searchapi.io/) 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>TimeoutError</code> – If the request to the SearchApi API times out.
- <code>SearchApiError</code> – If an error occurs while querying the SearchApi API.
