For more options, check out [Algolia DocSearch's documentation](https://docsearch.algolia.com/docs/behavior). You can pass any extra option alongside other options, e.g. passing `searchParameters`:

```js
module.exports = {
themeConfig: {
algolia: {
apiKey: 'your_api_key',
indexName: 'index_name',
searchParameters: {
facetFilters: ['tags:guide,api']
}
}
}
}
```

## Internationalization (i18n)

If you have multiple locales in your documentation and you have defined a `locales` object in your `themeConfig`:

```js
module.exports = {
themeConfig: {
locales: {
// ...
},
algolia: {
apiKey: 'your_api_key',
indexName: 'index_name'
}
}
}
```

VitePress will automatically add a `language` _facetFilter_ to the `searchParams.facetFilter` array with the correct language value. **Make sure to properly configure your DocSearch config as well** by adding `language` as a _custom attribute for faceting_ and by setting it based on the `lang` attribute of the `<html>` element. Here is a short example of DocSearch config:

```json
{
"index_name": "<the name of your library>",
"start_urls": [
{
"url": "<your deployed url>"
}
],
"stop_urls": ["(?:(?<!\\.html)(?<!/))$"],
"selectors": {
"lvl0": {
"selector": ".sidebar > .sidebar-links > .sidebar-link .sidebar-link-item.active",
"global": true,
"default_value": "Documentation"
},
"lvl1": ".content h1",
"lvl2": ".content h2",
"lvl3": ".content h3",
"lvl4": ".content h4",
"lvl5": ".content h5",
"lvl6": ".content p, .content li",
"text": ".content [class^=language-]",
"language": {
"selector": "/html/@lang",
"type": "xpath",
"global": true,
"default_value": "en-US"
}
},
"custom_settings": {
"attributesForFaceting": ["language"]
}
}
```

You can take a look at the [DocSearch config used by Vue Router](https://github.com/algolia/docsearch-configs/blob/master/configs/next_router_vuejs.json) for a complete example.
