## RetrievalToolkit

```python theme={"system"}
class RetrievalToolkit(BaseToolkit):
```

A class representing a toolkit for information retrieval.

This class provides methods for retrieving information from a local vector
storage system based on a specified query.

<a id="camel.toolkits.retrieval_toolkit.RetrievalToolkit.__init__" />

### **init**

```python theme={"system"}
def __init__(
    self,
    auto_retriever: Optional[AutoRetriever] = None,
    timeout: Optional[float] = None
):
```

Initializes a new instance of the RetrievalToolkit class.

### information\_retrieval

```python theme={"system"}
def information_retrieval(
    self,
    query: str,
    contents: Union[str, List[str]],
    top_k: int = Constants.DEFAULT_TOP_K_RESULTS,
    similarity_threshold: float = Constants.DEFAULT_SIMILARITY_THRESHOLD
):
```

Retrieves information from a local vector storage based on the
specified query. This function connects to a local vector storage
system and retrieves relevant information by processing the input
query. It is essential to use this function when the answer to a
question requires external knowledge sources.

**Parameters:**

* **query** (str): The question or query for which an answer is required.
* **contents** (Union\[str, List\[str]]): Local file paths, remote URLs or string contents.
* **top\_k** (int, optional): The number of top results to return during retrieve. Must be a positive integer. Defaults to 1.
* **similarity\_threshold** (float, optional): The similarity threshold for filtering results. Defaults to 0.7.

**Returns:**

str: The information retrieved in response to the query, aggregated
and formatted as a string.

```

**Returns:**

List\[FunctionTool]: A list of FunctionTool objects
representing the functions in the toolkit.
