+### Extra Search Options
+
+You can also specify extra [search options used by Algolia](https://community.algolia.com/docsearch/documentation/) by using an `algoliaOptions` field in `algolia`. This may be useful if you want to provide different search results for the different versions or languages of your docs. More details about search options can be [found here](https://www.algolia.com/doc/api-reference/api-parameters/#overview).
+
+```js
+const siteConfig = {
+  ...
+  algolia: {
+    ...
+    algoliaOptions: '{ facetFilters: [ "tags:0.47" ], hitsPerPage: 5 }'
+  },
+}
+```

 ### Controlling the Location of the Search Bar
 
 By default, the search bar will be the rightmost element in the top navigation bar.
