Data Mining with Google

Basic Usage:
  • Use quotation marks " " to locate an entire string.
    eg. "bill gates conference" will only return results with that exact string.
  • Mark essential words with a +
    If a search term must contain certain words or phrases, mark it with a + symbol. eg: +"bill gates" conference will return all results containing "bill gates" but not necessarily those pertaining to a conference
  • Negate unwanted words with a -
    You may wish to search for the term bass, pertaining to the fish and be returned a list of music links as well. To narrow down your search a bit more, try: bass -music. This will return all results with "bass" and NOT "music".
