Internet Search TechniquesKaren Blakeman
RBA Information Services
Search engine meltdown
AlltheWeb Livesearch - gone– AlltheWeb itself still alive but no further development (uses
Yahoo databases) Ask – gone down hill since latest makeover Live.com
– link and linkdomain commands – now you see ‘em, now you don’t
– Academic Live, Live Books – gone Yahoo
– NOT command, parentheses, Mindset - gone Exalead
– Approximate spelling (transformed into smellslike, spell slike!)– ‘regular expression’ internal masking of letters - gone
Accoona – gone – http://www.rba.co.uk/wordpress/2008/10/05/accoona-is-no-more/

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operators– only OR works in Google and even that does not work well– Live.com, Exalead and MSE360 are best (Yahoo has withdrawn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)

Search techniques – a reminder
Repeat your key search terms in your strategy– chocolate production UK france belgium – chocolate production UK france belgium belgium belgium
• give different results Change the order of your terms
– chocolate production Belgium Switzerland – production Belgium Switzerland chocolate
• different results See the summary and comparison chart for the major search
engines at http://www.rba.co.uk/search/compare.pdf and http://www.rba.co.uk/search/compare.shtml

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
Run in at least Google, Yahoo and Live Looking for experts on a topic or presentations?
– Slideshare http://www.slideshare.net/– authorSTREAM http://www.authorstream.com/ – YouTube http://www.youtube.com/

Unique Google search features
Automatically looks for variations on your terms– to stop it, precede your terms with plus signs
e.g. air +pollution or put your term in double quotes e.g. “Smyth” Synonym search
– precede your search terms with a tilde (~) Numeric range search
– now on advanced search page
– can be weights, distances, years, prices
– Command line syntax is
• search term(s) first value..second value unit of measurement
– TV advertising spend forecasts 2005..2012– toblerone 1..5 kg
18 April 2023 Karen Blakeman www.rba.co.uk 7
Unique Google search features
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
– adding extra * changes the results– add, remove spaces between * * to change ranking of results
• why does it do that – who knows?– no information on maximum number of terms of separation

Cluuz
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
