51 21 May 2005Karen Blakeman Examples ■ Blinkx - ■ Ask Jeeves - sp.ask.com/docs/desktop/ ■ Google Desktop - desktop.google.com ■ MSN - ■ Copernic Desktop - ■ Yahoo desktop - desktop.yahoo.com

52 21 May 2005Karen Blakeman Desktop search - what is indexed? ■ Your documents, , cached web pages etc ■ How? – varies with search tool e.g. Google first creates a cache and then indexes the cache, others create just an index ■ First time indexing can take along time ■ Updates handled differently by different tools – scheduled e.g. every hour, once a day – continually as new or edited documents appear (dynamic indexing)  can interfere with work  need to be able to pause or "snooze" indexing if necessary

53 21 May 2005Karen Blakeman Document types supported ■ Varies depending on the desktop search tool ■ Crucial when choosing a tool ■ Usually at least MS Office, html, text files – may not support OpenOffice, Thunderbird, Eudora, Firefox, Netscape etc. – may only index default folders e.g. My documents ■ Preview will vary depending on type of document ■ Check treatment of secure web pages – https e.g. bank statements, Intranet pages ■ Check treatment of password protected docs

54 21 May 2005Karen Blakeman Also check... ■ Can the content of a particular document format be searched or is only title searched? ■ Can the tool support files without extensions? ■ Do you really need network or Enterprise Search rather than just local PC search? ■ Also check that you have at least the minimum spec on your machine to support the desktop search tool - some are resource hungry ■ Operating systems supported – MS, MAC, Linux?

57 21 May 2005Karen Blakeman Blinkx ■ "blinkx changes the way you interact with all kinds of information by reading the content on your computer screen and automatically linking you to related information - Web sites, the latest news on the Web, even documents and on your computer." ■ "Without having to actively or explicitly fire off a search or even choose words to search on, IQ uses intelligent analysis of the page a user is reading or writing to find related information, again regardless of its source, whether the local computer, the internet or television."

58 21 May 2005Karen Blakeman Blinkx ■ Limited range of file formats supported ■ Indexing is very slow ■ Memory hungry ■ Not intuitive ■ "Intelligent Analysis" loses the plot if you have a wide range of interests

73 21 May 2005Karen Blakeman

74 21 May 2005Karen Blakeman Should you install desktop search? ■ Security issues to consider and conflicts with document management policies ■ Safest one so far seems to be Yahoo ■ All limited in file types supported – Yahoo most comprehensive ■ Do not rely on desktop search to find your documents – far better to have well organised, structured documents folders

75 21 May 2005Karen Blakeman The future for desktop search ■ Limited take up at present in the corporate environment – some are specifically prohibited ■ Many tools need to improve drastically – many will not bother ■ Microsoft to integrate desktop search into the operating system ■ Will still need tools for non-Microsoft platforms and non-Microsoft document formats
