# SearXNG Tool

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.

{% hint style="info" %}
**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 <a href="#node-options" id="node-options"></a>

* **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](https://en.wikipedia.org/wiki/List_of_ISO_639_language_codes) 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 <a href="#running-a-searxng-instance" id="running-a-searxng-instance"></a>

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:

```yaml
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](https://docs.searxng.org/admin/installation-searxng.html#configuration).

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

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.n8n.io/integrations/builtin/cluster-nodes/sub-nodes/n8n-nodes-langchain.toolsearxng.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
