Re-sorting your search results: these should appear in order of those that are 'most relevant; but you can change this to appear order by date (starting with the most recently added). To do this, click the 'relevance' option just above your results and select 'date newest'.
Retrieving only a few results? Return to the search boxes at the top of the screen. Consider whether there are any further alternative keywords that could be added. Also consider whether any of the concepts that you originally identified are of only marginal relevance to your research - if so, remove the associated set(s) of keywords.
Retrieving too many irrelevant results? Return to the search boxes at the top of the screen. Consider whether any individual keywords are of only marginal relevance – if so, remove these and try another search. Also consider whether a further concept needs to appear in each search result. If so, add another search box and enter the concept's associated keyword(s). The database's filter options can also help you refine your results (read the next section).
You can run separate searches, each on a different theme, and then combine the sets of results. To do this, go the search history section which appears just below the search boxes. Here you will find a list of each of your searches (from your current search session) and each search is given a corresponding #number.
In the 'combine queries' box, enter the relevant #numbers that you wish to combine. Then enter one of the following in between the #numbers: AND, OR, NOT (for example, you might enter #1 AND #2). Finally, click the magnifying glass to retrieve the new set of results.
