2 Search engine meltdown  AlltheWeb Livesearch - gone –AlltheWeb itself still alive but no further development (uses Yahoo databases)  Ask – gone down hill since latest makeover  –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 – 09 May 2015Karen Blakeman

4 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for the operators –only OR works in Google and even that does not work well –, Exalead and MSE360 are best (Yahoo has withdrawn NOT, and nested Boolean) –for example chemical engineer AND (inurl:cv OR intitle:cv) AND (oil OR petroleum) 09 May 2015Karen Blakeman

5 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 and 09 May 2015Karen Blakeman

7 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 09 May 2015Karen Blakeman

8 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 09 May 2015Karen Blakeman
