GoogleSearch Component

The biggest challenge for AI used to be its tendency to present vague, outdated, or downright false information. All these issues are simply caused by a lack of access to relevant knowledge. In the past, fixing this issue required training the entire model anew, which was unthinkable for most businesses, let alone individuals. But there’s a different approach, allowing you to simply point the models to the right knowledge sources on the go.

This approach is called the Retrieval-Augmented Generation (RAG), and it allows you to supply generative models with additional knowledge on the go without any technical skills or the need to train entire models. The retrieval components, including GoogleSearch, allow you to use this method easily.

What is the GoogleSearch component?

This component allows the flow to retrieve knowledge by searching Google for relevant content. It specifies the search query and dictates how the flow retrieves the information. It can be used concurrently with other retrieval components to enhance the final answer.

Example Use Cases

• Real-Time Fact Checking: Use the component to verify claims or gather the latest news articles on a topic.
• Content Augmentation: Automatically fetch relevant external resources for document enrichment.
• AI Agents: Equip conversational agents with the ability to pull in fresh knowledge from the web. Domain-Specific Search: Restrict searches to specific websites using the query prefix functionality (e.g., site:arxiv.org for academic papers).

Why Use This Component?

• Stay Current: Access the most recent information from the web, overcoming the limitations of static training data.
• Flexible Configuration: Tailor the search to your country, language, and location needs.
• Workflow Integration: Outputs are compatible with other components, making it easy to build complex, knowledge-enabled AI processes.
• Caching: Improves efficiency by avoiding redundant searches when the same query is repeated.

Input Query

Specifies the query that’s used to look up relevant information. It can be linked from a component, such as Chat Input, or inputted manually.

Results Limit

This setting limits the number of links crawled for information. Google has extensive algorithms to rank results and ensure the top ones are the most relevant to the query. The top five results should be plenty for the flow to get relevant information and craft a meaningful response to most queries.

Language

If your website is in a specific language, the chatbot returning results in English would do more harm than good. Moreover, niche and local topics may give more relevant results when searched in the correct language.

Country

Setting the country is another line of defense ensuring relevant results. Imagine you have a financial advice chatbot, and a user asks about tax laws. Only setting the language could result in a person from the UK getting information about US tax laws, resulting in confusion and frustration.

Location

This optional setting allows you to narrow down the results even more. Returning results relevant only to a specific city or region is beneficial for some use cases.

Query prefix

Query prefixes are specific words or symbols you can use to narrow down the type of results. For example, you might use the “daterange:” prefix to ensure the results are recent or the “filetype:” prefix if you want a specific file format. Google supports a range of these prefixes, allowing for great control over the returned results.

How to connect the GoogleSearch component to your flow

The component contains just one input and one output handle:

• Input Query: The query can be any text output. Common use cases would be connecting Chat Input or a Generator.
• Output: The output of any retriever-type component is always a Document.

The Document output can only be read by the Document to Text and Widget-type components. These transform the raw search results into a presentable form ready for output.

Creating a Flow using GoogleSearch

Let’s create a simple chatbot utilizing Google Search as its main source of knowledge.

1. As always, start with Chat Input.
2. Connect the input to the GoogleSearch component, meaning the human query is the search prompt.
3. Transform the retriever output. The output is a URL record; we want it to be plain text. Use the URL Retriever component.
4. You can optionally add Prompt and Chat History. We will do so, as it makes the output nicer and more conversational.
5. Connect the Generator to add an LLM to the mix.
6. You’re ready to output.

Here’s our resulting Flow:

Let’s ask the GoogleSearch bot what the best AI model is:

The bot returns a list of the best models, commenting on each and listing the sources. We purposefully limited the length of output to fit the chat window. However, the result may be much more elaborate than this.
