    4. Google’s ‘advanced operators’ are used to pin-point results that normal search strategies can’t reach You can use Google’s ‘advanced’ search form, but used correctly, operators can cut to the chase faster, giving you better and more focused results Friday, 19 June 2009 4
    5. Precision Surfing using google’s advanced operators • Use advanced operators for more precision and flexibility. • Type them directly into the google search field • Command google to look only: • at specific sites; • for specific document types; or, • for search terms in specific places. Friday, 19 June 2009 5
    6. Look at this search string: business opportunities “london olympics” ~advice site:.com • site:.com restricts the search to ‘.com’ websites only. • ~advice searches for synonyms of advice such as ‘help’ or ‘guide’ • “london olympics” acts as a phrase search Friday, 19 June 2009 6
