Algolia is an enterprise-grade hosted search API that delivers search results in milliseconds. It offers typo tolerance, faceted search, custom ranking, and pre-built frontend UI libraries (InstantSearch.js).

Static websites can index their content during their CI build and query Algolia directly from the client browser using read-only search API keys.

Key Highlights & Features

• As-You-Type Speed: Instant search results returned in under 20 milliseconds.
• Smart Typo Tolerance: Finds accurate results even with spelling mistakes.
• InstantSearch.js: Pre-built, customizable search UI components.
• DocSearch Program: Free search service for qualifying open-source documentation.

Embed Algolia InstantSearch in a static HTML page:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/instantsearch.css@8/themes/satellite-min.css">
<script src="https://cdn.jsdelivr.net/npm/instantsearch.js@4"></script>

<div id="searchbox"></div>
<div id="hits"></div>

<script>
  const search = instantsearch({
    indexName: 'YOUR_INDEX_NAME',
    searchClient: algoliasearch('YOUR_APP_ID', 'YOUR_SEARCH_ONLY_API_KEY'),
  });

  search.addWidgets([
    instantsearch.widgets.searchBox({ container: '#searchbox' }),
    instantsearch.widgets.hits({ container: '#hits' })
  ]);

  search.start();
</script>
