I know, I know, we told you not to use Google for your assignments
However, Google has some great features for searching for government reports, policies, statistics and other useful documents. (But please do not rely on using Google for all your references.)
incidence "whooping cough" site:gov.au
Try it in Google
You can also:
incidence "whooping cough" site:vic.gov.au daterange:2014-2016 filetype:PDF
You can also use parentheses (round brackets) and OR for alternative terms (works best at the end of the search line):
incidence site:vic.gov.au daterange:2014-2016 filetype:PDF ("whooping cough" OR pertussis)
Remember about using professional or technical terms to find professional results? Try leaving out whooping cough and only searching for the medical term for the condition, pertussis.
incidence site:vic.gov.au daterange:2014-2016 filetype:PDF pertussis
We can also exclude a search term from our results (similar to using NOT in a database) by putting a hyphen or minus sign in front of the word (or phrase in quotes). For example, to exclude results that include the word Melbourne, we can use -Melbourne
incidence site:vic.gov.au daterange:2014-2016 filetype:PDF pertussis -Melbourne
Warning: excluding results that have the word Melbourne will also exclude results that have Melbourne and rural details, or Melbourne and your area of interest.
