• Copy the following CSS/JS snippets and add them to your page

<!-- at the end of the HEAD -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/docsearch.js@2/dist/cdn/docsearch.min.css" />

<!-- at the end of the BODY -->
<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/docsearch.js@2/dist/cdn/docsearch.min.js"></script>

<script type="text/javascript">
 docsearch({
apiKey: 'd672449370ed94b6bb27a0ad6de65a60',
indexName: 'hugoloveit',
inputSelector: '### REPLACE ME ####',
algoliaOptions: { 'facetFilters': ["lang:$LANG"] },
debug: false // Set debug to true if you want to inspect the dropdown
});
</script>

• Add a search input in your page if you don't have any yet. Then update the inputSelector value in JS snippet to a CSS selector that targets your search input field.

• Replace $LANG with the lang you want to search on. The list of possible lang is extracted from your website according to the "lang" selector. So as of today you have: en, fr, zh-cn

For example if you want to refine the search to the lang "en" just specify: 'facetFilters': ["lang:en"]

• Optionally customize the look and feel by following the DocSearch documentation (See https://community.algolia.com/docsearch/styling.html)
• You can also check your configuration in our GitHub repository (See https://github.com/algolia/docsearch-configs/blob/master/configs/hugoloveit.json).
