Return to the search screen at any time by clicking the Search tab. From the Search screen, beneath the search box you will see your search history, a list of all the searches you have carried out during that session. You can re-run any of the older searches by clicking on the number of results for that line.
You can also combine searches by following the "advanced document search" link, scrolling down, and following the example in the 'Combine queries...' box.
For example, if we have carried out a search on wellbeing OR "quality of life" and another on countryside OR "green space", these will appear in our search history as search 1 and search 2. We can combine these two searches together by entering #1 AND #2 in the 'Combine queries...' search box.
Search operators explained
The search operators AND and OR are used in searching to combine search terms together.
AND retrieves articles which contain all of your concepts. For example, if you are interested in the use of cognitive behaviour therapy for gambling disorders, you would search for cognitive behaviour therapy AND gambling.
OR retrieves records which contain any of your concepts. For example, you might search for cognitive behaviour therapy OR CBT to retrieve all articles on the topic.
