Google Search Rules A Close Look at Google of page with your terms Search Results •• Excerpt Matched terms in bold • Which Google database used • Approx. # of hits • Terms actually searched on, as Dictionary links • URL, size, date last crawled • Link to Cached copy • Pages supposedly like this one • 2nd page from same site • All Google pages from this site Don’t believe the number of Results They are approximate, changing, and not comprehensive Performing Better Google Searches Use Search Operators AND not needed; default between terms OR includes either of two terms (OR must be in caps) (space and a - for NOT) (e.g. Michigan –lake) “ ” search a phrase in quotes (e.g. “search engine”) ~ synonym search (e.g. ~pets retrieves cats, dogs ..) .. Number range (e.g. super bowl 1975..1978) * Google does not allow truncation. An * replaces an entire word in a search.
