Search techniques a reminder
Search techniques – a reminder

  • Search engines still search for all of your terms by default

    • but note that Google also looks for terms in ‘links to’

  • Double quote marks around phrases

    • e.g. “climate change”

  • To exclude pages containing a term, precede the term with a minus sign (-)

  • Boolean search

    • OR, AND, NOT

    • must use capital letters for the operators

    • only OR works in Google and even that does not work well

    • Live.com, Exalead and MSE360 are best (Yahoo has withdrawn NOT, and nested Boolean)

    • for example chemical engineer AND (inurl:cv OR intitle:cv) AND (oil OR petroleum)

  • http://www.cluuz.com/

  • “Cluuz … core technology understands the relationship between the entities, terms, or persons searched leading to more relevant, easy to understand search results”

  • Not totally intuitive but the network visualisation is ‘cool’

  • The links in the network visualisation do not always relate to the same person or organisation but they are usually working in a similar field or subject area

  • Results change from one day to the next, one hour to the next, but still worth a look
