Use Google Search API

Add a web search to your pipelines using Google Search API.

You can add a search engine that uses Google's Search API to your pipelines.

Prerequisites

You need an API key from Google Search API.

Use Search API

First, connect deepset Cloud to SearchApi through the Connections page:

Click your initials in the top right corner and select Connections.
Click Connect next to the provider.
Enter your user access token and submit it.

Then, add the SearchApiWebSearch component to your pipeline. This component uses page snippets to find relevant pages and returns a list of URLs. It's typically used before a LinkContentFecther or Converters.

Usage Examples

This is an example of an indexing pipeline that uses SearchApi:

components:
...
    web_retriever:
      type: haystack.components.websearch.searchapi.SearchApiWebSearch
      init_parameters:
       top_k: 20
    
    link_fetcher:
      type: haystack.components.fetchers.link_content.LinkContentFetcher
      init_parameters: {} # we're leaving the default value parameters        

    html_converter:
      type: haystack.components.converters.html.HTMLToDocument
      init_parameters:
        # A dictionary of keyword arguments to customize how you want to extract content from your HTML files.
        # For the full list of available arguments, see
        # the [Trafilatura documentation](https://trafilatura.readthedocs.io/en/latest/corefunctions.html#extract).
        extraction_kwargs:
          output_format: txt  # Extract text from HTML. You can also also choose "markdown"
          target_language: null  # You can define a language (using the ISO 639-1 format) to discard documents that don't match that language.
          include_tables: true  # If true, includes tables in the output
          include_links: false  # If true, keeps links along with their targets
          ...
 
connections:
...
- sender: web_retriever.links
- receiver: link_fetcher.urls
- sender: link_fetcher.urls
- receiver: html_converter.sources
...
