+The `algolia` option allows you to use [algolia docsearch](https://github.com/algolia/docsearch) to replace the simple built-in search. To enable it, you need to provide at least `apiKey` and `indexName`:
+
+```js
+module.exports = {
+  algolia: {
+    apiKey: '<API_KEY>',
+    indexName: '<INDEX_NAME>'
