Open Search is a technology which allows to create your own browsing engine used by a browser. Thanks to it, e.g. in a Firefox browser, a user may define a new browser after entering our website based on GavernWP framework. Because of it, in the case of more extensive websites, e.g. data catalogs, searching is much easier.
Switching on support for Open Search requires switching on one option in an administration panel in a tab of advanced settings. All other operations are made with GavernWP.
