# SearchApi Tool
|
|
|
|
The [SearchApi](https://www.searchapi.io/) allows developers to retrieve results from search engines such as Google, Google Scholar, YouTube, YouTube transcripts, and more, and can be used as in Langflow through the `SearchApi` tool.
|
|
|
|
<Admonition type="info">
|
|
To use the SearchApi, you must first obtain an API key by registering at [SearchApi's website](https://www.searchapi.io/).
|
|
</Admonition>
|
|
|
|
In the given example, we specify `engine` as `youtube_transcripts` and provide a `video_id`.
|
|
|
|
<Admonition type="info">
|
|
All engines and parameters can be found in [SearchApi documentation](https://www.searchapi.io/docs/google).
|
|
</Admonition>
|
|
|
|
The `RetrievalQA` chain processes a `Document` along with a user's question to return an answer.
|
|
|
|
<Admonition type="tip">
|
|
In this example, we used [`ChatOpenAI`](https://platform.openai.com/) as the
|
|
LLM, but feel free to experiment with other Language Models!
|
|
</Admonition>
|
|
|
|
The `RetrievalQA` takes `CombineDocsChain` and `SearchApi` tool as inputs, using the tool as a `Document` to answer questions.
