Dear Wiki user, You have subscribed to a wiki page or wiki category on "Nutch Wiki" for change notification.
The following page has been changed by MichaelStack: http://wiki.apache.org/nutch/FAQ The comment on the change is: Added 'What is the RSS symbol in search results all about?' ------------------------------------------------------------------------------ Anchor text makes a large contribution to document score (You can see the anchor text for a page by browsing to "explain" then editing the URL to put in place "anchors.jsp" in place of "explain.jsp"). + ==== What is the RSS symbol in search results all about? ==== + Clicking on the RSS symbol sends the current query back to Nutch to a servlet named OpenSearchServlet that redoes the search returning the results instead formatted as RSS (XML). The RSS format is based on [http://a9.com/-/spec/opensearchrss/1.0/ OpenSearch RSS 1.0] from [http://www.a9.com a9.com] (Also see [href="http://opensearch.a9.com/ OpenSearch]). Nutch extensions add to the OpenSearch RSS the original query, navigation information, and any extra fields that available in the search result such as Nutch boost, segment name, etc. + + Results as RSS (XML) rather than HTML are easier for programmatic clients to parse: such clients will query against OpenSearchServlet rather than search.jsp. Results as XML can also be transformed using XSL stylesheets, the likely direction of UI development in nutch going by mailing list posts. + === Crawling ===
