About

OpenSearch is a specification that describes a website's search engine, enabling browsers, apps, and services to discover and integrate it.

It is implemented as a linked XML file and was originally developed by Amazon to make it easier for other applications to integrate their search services.

SearchAction is a structured data type from Schema.org that describes a website's search capability.

Before November 2024, it was used by Google to enable the "Sitelinks Search Box" feature, which displayed a search bar for a website directly within the search results snippet. However, since Google deprecated this feature, there is no evidence that other search engines or apps currently support it.
