# `CodeDocsSearchTool`

<Note>
    **Experimental**: We are still working on improving tools, so there might be unexpected behavior or changes in the future.
</Note>

## Description

The CodeDocsSearchTool is a powerful RAG (Retrieval-Augmented Generation) tool designed for semantic searches within code documentation. 
It enables users to efficiently find specific information or topics within code documentation. By providing a `docs_url` during initialization, 
the tool narrows down the search to that particular documentation site. Alternatively, without a specific `docs_url`, 
it searches across a wide array of code documentation known or discovered throughout its execution, making it versatile for various documentation search needs.

## Installation

To start using the CodeDocsSearchTool, first, install the crewai_tools package via pip:

```shell
pip install 'crewai[tools]'
```

## Example

Utilize the CodeDocsSearchTool as follows to conduct searches within code documentation:

```python Code
from crewai_tools import CodeDocsSearchTool

# To search any code documentation content 
# if the URL is known or discovered during its execution:
tool = CodeDocsSearchTool()

# OR

# To specifically focus your search on a given documentation site 
# by providing its URL:
tool = CodeDocsSearchTool(docs_url='https://docs.example.com/reference')
```
<Note>  
    Substitute 'https://docs.example.com/reference' with your target documentation URL 
    and 'How to use search tool' with the search query relevant to your needs.
</Note>

## Arguments

The following parameters can be used to customize the `CodeDocsSearchTool`'s behavior:

| Argument       | Type     | Description                                                                                                                         |
|:---------------|:---------|:-------------------------------------------------------------------------------------------------------------------------------------|
| **docs_url**    | `string` | _Optional_. Specifies the URL of the code documentation to be searched.                                                | 

## Custom model and embeddings

By default, the tool uses OpenAI for both embeddings and summarization. To customize the model, you can use a config dictionary as follows:

```python Code
tool = CodeDocsSearchTool(
    config=dict(
        llm=dict(
            provider="ollama", # or google, openai, anthropic, llama2, ...
            config=dict(
                model="llama2",
                # temperature=0.5,
                # top_p=1,
                # stream=true,
            ),
        ),
        embedder=dict(
            provider="google-generativeai", # or openai, ollama, ...
            config=dict(
                model_name="gemini-embedding-001",
                task_type="RETRIEVAL_DOCUMENT",
                # title="Embeddings",
            ),
        ),
    )
)
```
