@docusaurus/preset-classic supports a search integration.
There are two main options, you can use Algolia DocSearch or bring in your own
Algolia DocSearch works by crawling the content of your website every 24 hours and putting all the content in an Algolia index. This content is then queried directly from your front-end using the Algolia API. Note that your website needs to be publicly available for this to work (i.e., not behind a firewall). The service is free.
To connect your docs with Algolia, add an
algolia field in your
themeConfig. Apply for DocSearch to get your Algolia index and API key.

Contextual search is mostly useful for versioned Docusaurus sites.
Let's consider you have 2 docs versions, v1 and v2. When you are browsing v2 docs, it would be odd to return search results for the v1 documentation. Sometimes v1 and v2 docs are quite similar, and you would end up with duplicate search results for the same query (one result per version).
To solve this problem, the contextual search feature understands that you are browsing a specific docs version, and will create the search query filters dynamically.
/docs/v1/myDoc, search results will only include v1 docs (+ other unversioned pages)
/docs/v2/myDoc, search results will only include v2 docs (+ other unversioned pages)
If you decide to use contextual search, you can't provide
algolia.searchParameters.facetFilters, as we compute this
facetFilters attribute for you dynamically.
By default, DocSearch comes with a fine-tuned theme that was designed for accessibility, making sure that colors and contrasts respect standards.
Still, you can reuse the Infima CSS variables from Docusaurus to style DocSearch by editing the
