OpenSearch is a collection of technologies that allow publishing of search results in a format suitable for syndication and aggregation. It is a way for websites and search engines to publish search results in a standard and accessible format.

OpenSearch was developed by Amazon.com subsidiary A9 and the first version, OpenSearch 1.0, was unveiled by Jeff Bezos at the O'Reilly Emerging Technology Conference in March, 2005. Draft versions of OpenSearch 1.1 were released during September and December 2005. The OpenSearch specification is licensed by A9 under the Creative Commons Attribution-ShareAlike 2.5 License.[1]

Support

Web browsers that support OpenSearch include Safari,[2] Microsoft Edge,[3] Firefox[4] and Google Chrome.[5]

Design

OpenSearch consists of:

  1. OpenSearch Description files: XML files that identify and describe a search engine.
  2. OpenSearch Query Syntax: describe where to retrieve the search results
  3. OpenSearch RSS (in OpenSearch 1.0) or OpenSearch Response (in OpenSearch 1.1): format for providing open search results.
  4. OpenSearch Aggregators: Sites that can display OpenSearch results.
  5. OpenSearch "Auto-discovery" to signal the presence of a search plugin link to the user and the link embedded in the header of HTML pages

OpenSearch Description Documents list search result responses for the given website/tool. Version 1.0 of the specification only allowed one response, in RSS format; however, version 1.1 provides support for multiple responses, which may be in any format. RSS and Atom are the only ones formally supported by OpenSearch aggregators, however other types, such as HTML are perfectly acceptable.

  • Auto-discovery of an OpenSearch Description Document is available from both HTML and Atom or RSS feed documents via Link relations in the form of for Atom feeds[6] or for RSS feeds[6] and HTML documents.[7]
  • OpenSearch Description Document must be placed on a web server of the same domain.[8]
  • OpenSearch Description Documents must be served with the application/opensearchdescription+xml Internet media type.[9]
