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operators– only OR works in Google and even that does not work well– Live.com, Exalead and MSE360 are best (Yahoo has withdrawn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

Ask
http://www.ask.com/, http://www.ask.co.uk/ Suggestions for narrowing down or expanding your search Particularly good for blogs Big News gone Search interface and options revamped
http://www.live.com/ Results tend to be more consumer oriented Has the most up to date database Possibly has the most extensive database of web pages Good image search option Feed command for locating RSS feeds on a specified web
site– site:bbc.co.uk feed:bbc.co.uk
Revamped interface but no improvement in advanced search screen
Link commands gone Axed Link commands, Books and Academic Live
BBC – http://news.bbc.co.uk/ Search engine news options e.g. Yahoo, Google
– have only the last 30 days of free news– advanced search options limited and unreliable– no source list, and sources frequently change– key industry publications may not be included
Google News Archive http://www.google.com/archivesearch– some sources going back 200 years
– many articles are priced (before you buy check other sources)
View the ‘references’ (web pages) to see the information in context

Cluuz

“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
