Google announced new features for the Google Search Appliance that give enterprise customers the ability to customize search results for their individual corporate environments. The Google Search Appliance now also offers improved integration with Google services as well as additional content sources. New features include Results Hit Clustering and Source Biasing. Results Hit Clustering are groups of dynamically formed sub-categories based on the results of each search query. These clusters appear at the top of search results and help searchers refine their queries from possible ambiguous terms. For example, if an employee searches for “customer” on the company network, a set of categories could appear at the top of the results with groups of topics such as “customer support” or “customer contacts” to help guide the search. Administrators can customize the location and appearance of Results Hit Clustering within search results. Source Biasing enables administrators to assign various weights to search results on their corporate network, based on source or type of content. For instance, if a company has multiple Documentum servers, the site administrator can strengthen the content from the one primary Documentum server. The same is true for types of content. If a financial services corporation values content in .pdf form more than content in a word processing document, administrators can use Source Biasing to increase the weight of .pdfs in the search results. A menu-driven interface allows weak or strong increases or decreases, and requires no complex coding or scripting. The new version of the Google Search Appliance also adds improved integration with Google Sitemaps export (for simpler export of information about web pages available for crawling), as well as open source connectors for indexing content in SharePoint 2003 and SharePoint 2007. http://www.google.com/enterprise/gsa/
