Search Engine Referrals Confluence Plugin is a Confluence plugin that displays the most recent searches on Google. When someone enters search terms on Google and clicks on one of the search results, the search terms are sent to the found Web site in the "referer" part of the HTTP request. This plugin collects this information and displays it to the user. A click on the search result opens the page Google has found. A click on the search engine icon at the left displays the corresponding Google search result page.
