Better searching in Google...

…can be achieved by using just a few simple search tips. Take the following example: you want to find UK government publications on the future treatment of schizophrenia. While there is no ‘correct’ way of searching for this on Google, I would recommend typing in: 

schizophrenia site:gov.uk OR site:nhs.uk filetype:pdf OR filetype:doc 2011..2025

So what does all that mean?

schizophrenia is the keyword.
site:gov.uk OR site:nhs.uk means that we only want to see results coming from UK government or NHS websites.
filetype:pdf OR filetype:doc means we only want PDF or Word files – the most common format for publications i.e. we don’t want webpages to be returned - we want documents.
2011..2025 is a number range identifying that we want documents which state a date in the future to appear in them (i.e. any date in the range 2011 to 2025).
