What does enabling OpenSearch do in Confluence?

• A. Enables in-page search across all spaces
• B. Creates a new site-wide search index
• C. Allows you to add Confluence as a search provider to some web browsers
• D. Enables mobile search only

Answer: (C)

OpenSearch in Confluence enables browsers to recognize Confluence as a search provider. This standard lets the browser expose Confluence as an available search option in the browser's search box, so you can add Confluence to your browser’s list of search providers and run queries directly from the browser.

This is different from Confluence’s own in-page search across spaces, which is about searching within the site itself. It also isn’t about creating a new site-wide search index or being limited to mobile devices; those relate to Confluence’s internal indexing or platform-specific behavior. The essence of enabling OpenSearch is to provide a browser-integrated search experience that lets you query Confluence from the browser’s search field.
