SearXNG Tool node#

The SearXNG Tool node allows you to integrate search capabilities into your workflows using SearXNG. SearXNG aggregates results from multiple search engines without tracking you.

On this page, you'll find the node options for the SearXNG Tool node, and links to more resources.

Parameter resolution in sub-nodes

Sub-nodes behave differently to other nodes when processing multiple items using an expression.

Most nodes, including root nodes, take any number of items as input, process these items, and output the results. You can use expressions to refer to input items, and the node resolves the expression for each item in turn. For example, given an input of five name values, the expression {{ $json.name }} resolves to each name in turn.

In sub-nodes, the expression always resolves to the first item. For example, given an input of five name values, the expression {{ $json.name }} always resolves to the first name.

Node Options#

  • Number of Results: The number of results to retrieve. The default is 10.
  • Page Number: The page number of the search results to retrieve. The default is 1.
  • Language: A two-letter language code to filter search results by language. For example: en for English, fr for French. The default is en.
  • Safe Search: Enables or disables filtering explicit content in the search results. Can be None, Moderate, or Strict. The default is None.

Running a SearXNG instance#

This node requires running the SearXNG service on the same network as your n8n instance. Ensure your n8n instance has network access to the SearXNG service.

This node requires results in JSON format, which isn't enabled in the default SearXNG configuration. To enable JSON output, add json to the search.formats section of your SearXNG instance's settings.yml file:

1
2
3
4
5
search:
  # options available for formats: [html, csv, json, rss]
  formats:
    - html
    - json

If the formats section isn't there, add it. The exact location of the settings.yml file depends on how you installed SearXNG. You can find more by visiting the SearXNG configuration documentation.

The quality and availability of search results depend on the configuration and health of the SearXNG instance you use.

  • completion: Completions are the responses generated by a model like GPT.
  • hallucinations: Hallucination in AI is when an LLM (large language model) mistakenly perceives patterns or objects that don't exist.
  • vector database: A vector database stores mathematical representations of information. Use with embeddings and retrievers to create a database that your AI can access when answering questions.
