What Google's homepage may look like in
2084www.nytimes.com/imagepages/2005/10/10/opinion
/1010opart.html
4
Two points to remember..
  • Google et al do not exist to help you find
    information
  • Search engines, and in particular Google, are
    temperamental beasts
  • Do not attempt to apply logic to the way
    they work therein lies the path to madness

5
Types of search tools
  • Humans
  • is colleague or a friend already working or has
    worked in the subject area?
  • who have you met at meetings, conferences?
  • discussion lists, trade/professional
    associations, bloggers, LinkedIn, Facebook etc.
  • Search engines
  • different options for different types of
    information e.g. news, images
  • Evaluated listings, subject listings, types of
    information
  • Databases and peer reviewed sources
  • multi search engine tools
  • search many search tools at once
  • or type in your search once and click on each
    search tool in turn

6
How up to date are search engines?
  • Not very
  • You are searching an out of date index of the web
    and not the live web itself
  • May takes days to months for a site to be added
    to the index
  • Hierarchy of sites for updating
  • Some tools keep links to dead pages for a long
    time
  • Least up to date
  • Google
  • Most up to date
  • Live Search, Yahoo

7
A search engines results may vary
  • In content and presentation
  • from one minute to the next
  • different server being used
  • testing out different search and ranking
    algorithms
  • Country versions
  • different emphasis
  • local content
  • different interface
  • different search features

General search techniques
  • By default, the major search tools look for all
    of your terms in a page
  • Use double quote marks around phrases
  • e.g. climate change
  • To exclude pages containing a term, precede the
    term with a minus sign (-) use with care
  • Boolean search
  • OR, AND, NOT
  • must use capital letters for the operators
  • only OR works in Google and even that does not
    work well but worth trying more complex searches
  • Live.com, MSE360 and Exalead are best (Yahoo has
    withdrawn NOT and nested searches no longer work
    correctly
  • for example (directory OR directories OR
    database) AND (oil OR petroleum) AND Norway

10
General search techniques (2)
  • Focus your search on areas of the document
  • inurl for example inurlclimate change
  • looks for your terms in the URL
  • intitle for example intitleclimate change
  • looks for your term in the title of the page
  • Search sites or domains using the site command
  • chocolate labelling regulations siteeuropa.eu
  • Imagine what you would like to appear in your
    ideal document and include those terms in your
    strategy
  • Partially answer your question in your strategy
  • A hippopotamus can run at
  • Use the file formats and domain search to refine
    your search

11
File format search
  • Use advanced search options to limit your search
    to file types or format
  • pdf or doc for government or industry/market
    reports
  • xls for data and statistics
  • ppt or pdf for presentations
  • Search in at least Google and Yahoo, also
    consider Live.com
  • Looking for experts on a topic, presentations, a
    how to guide, general background on a subject,
    information on an organisation
  • advanced search ppt or pdf format
  • Slideshare http//www.slideshare.net/
  • authorSTREAM http//www.authorstream.com/
  • YouTube http//www.youtube.com/

12
Advanced Search options can vary depending on the
country version of Google
13
General search techniques (3)
  • Repeat your key search terms in your strategy
  • chocolate production france belgium austria
  • chocolate production austria france belgium
    belgium belgium
  • give different results
  • In Google can enter up to 32 terms, Yahoo 250
    characters
  • Change the order of your terms
  • chocolate production france belgium austria
  • production france belgium austria chocolate
  • different results
  • See the summary and comparison chart for the
    major search engines at http//www.rba.co.uk/searc
    h/compare.pdf and http//www.rba.co.uk/search/comp
    are.shtml

14
Unique Google search features
  • Automatically looks for variations on your terms
  • to force and exact match precede your terms with
    plus signs e.g. air pollution
  • Synonym search
  • precede your search terms with a tilde () e.g.
    banking
  • only works on English terms
  • Numeric range search
  • can be weights, distances, years, prices
  • use Advanced Search screen
  • or the search box on the Google home page
  • search term(s) first value..second value unit of
    measurement
  • toblerone 1..5 kg
  • TV advertising spend forecasts 2009..2015

15
Unique Google search features (2)
  • Proximity
  • use the asterisk () to stand in for one or more
    terms
  • macular degeneration picks up
  • macular retinal degeneration
  • macula disciform degeneration
  • macular choroidal degeneration
  • macular vitelliform degeneration
  • macular pigmentary degeneration
  • separates the terms by one or more words
  • no information on maximum number of terms of
    separation

16
Google oddity
  • Why does
  • sitewww.nhsdirect.nhs.uk macular degeneration
  • give 37 results
  • but
  • Sitewww.nhsdirect.nhs.uk macular degeneration
  • give

17
Google oddity
  • When the results are displayed click on Advanced
    Search

Google sees the capital S in the Site
command and decides that the site search is a
phrase search!
18
Google - Whats New
  • Knol A unit of knowledge
  • competing with Wikipedia
  • http//knol.google.com/
