## Overview When you give `BraveWebSearch` a query, it uses the [Brave Search API](https://brave.com/search/api/) to search the web and return relevant content as Haystack `Document` objects. It also returns a list of the source URLs. Brave Search is an independent search engine with its own web index. It is a great fit for RAG pipelines that need reliable, privacy-focused web results without depending on Google or Bing. `BraveWebSearch` requires a Brave Search API key to work. By default, it looks for a `BRAVE_API_KEY` environment variable. Alternatively, you can pass an `api_key` directly during initialization. ## Usage ### On its own Here is a quick example of how `BraveWebSearch` searches the web based on a query and returns a list of Documents. ```python from haystack_integrations.components.websearch.brave import BraveWebSearch from haystack.utils import Secret web_search = BraveWebSearch( api_key=Secret.from_env_var("BRAVE_API_KEY"), top_k=5, ) query = "What is Haystack by deepset?" response = web_search.run(query=query) for doc in response["documents"]: print(doc.content) ``` ### In a pipeline Here is an example of a Retrieval-Augmented Generation (RAG) pipeline that uses `BraveWebSearch` to look up an answer on the web. ```python from haystack import Pipeline from haystack.utils import Secret from haystack.components.builders.chat_prompt_builder import ChatPromptBuilder from haystack.components.generators.chat import OpenAIChatGenerator from haystack_integrations.components.websearch.brave import BraveWebSearch from haystack.dataclasses import ChatMessage web_search = BraveWebSearch( api_key=Secret.from_env_var("BRAVE_API_KEY"), top_k=3, ) prompt_template = [ ChatMessage.from_system("You are a helpful assistant."), ChatMessage.from_user( "Given the information below:\n" "{% for document in documents %}{{ document.content }}\n{% endfor %}\n" "Answer the following question: {{ query }}.\nAnswer:", ), ] prompt_builder = ChatPromptBuilder( template=prompt_template, required_variables={"query", "documents"}, ) llm = OpenAIChatGenerator( api_key=Secret.from_env_var("OPENAI_API_KEY"), ) pipe = Pipeline() pipe.add_component("search", web_search) pipe.add_component("prompt_builder", prompt_builder) pipe.add_component("llm", llm) pipe.connect("search.documents", "prompt_builder.documents") pipe.connect("prompt_builder.prompt", "llm.messages") query = "What is Haystack by deepset?" result = pipe.run(data={"search": {"query": query}, "prompt_builder": {"query": query}}) print(result["llm"]["replies"][0].text) ```
