There are a number of techniques you can use while searching to get better and more relevant results.
Basic and advanced search
Basic search usually involves one search box, with a few options about searching a specific collection or field. This is great for general searching. When you have multiple keywords or complex search queries, using Advanced search can be helpful. This usually involves several different boxes for your different keywords, built-in search operators, and more options for field searching and limiters.
Most databases will have a link to Advanced Search next to their Basic search option. Advanced Search in Google Scholar is accessible from the menu.
Use these with your keywords to refine your searches and specify exactly what you want to find. These are most useful in journal databases and Primo Search. (Some of them won't work as well in Google Scholar.)
|Operator||How to use||Example|
|Boolean||Use AND to retrieve results that contain both of your search terms. This narrows your results.||police AND federal|
|Boolean||Use OR to retrieve results that contain any or all of your search terms. Use this with synonyms or variant terms to expand your results.||law OR legislation|
|Boolean||Using NOT to exclude irrelevant results.||intelligence NOT artificial|
|Phrase||Use quotation marks to search for a phrase.||"climate change"|
|Truncation||Search for terms with different word endings using an asterisk.||adapt* = adapts, adapting, adaptable, adaptation...|
|Wildcards||A question mark can be used to replace a single letter within a word||analy?e = analyse, analyze|
Field searching and limiters
Most databases will allow you to specify which field you want to search. Common fields include author, title, dates, and subject headings/topic, and these are usually available in both basic and advanced search.
Once you've searched, you can also limit your results by some of these fields. This is extremely useful if you want all of your articles to have been published within a certain date range, or for them all to be peer-reviewed. Look for these in the menus beside your search results.
These techniques can be combined to create a more sophisticated and controlled search strategy. Combining strategies together is called a search string you can see more examples in the following table.
|coastal AND erosion||Boolean|
|"climate change" AND surface AND corrosion||Boolean, phrase|
|(sea wall OR seawall) AND corrosion||Boolean, Grouping|
|"climate change" AND coast* AND (sea wall OR seawall)||Boolean, Grouping, Truncation, phrase|
A proximity search forces a database to find results where one search term appears within a certain number of words of another search term. The proximity operator varies according to the database.
Examples from an EBSCOhost database:
employability N3 higher education (N=near) This will find results where employability is within 3 words of higher education in any order
employability W3 higher education (W=within) This will find results where employability is within 3 words of higher education in the order in which you entered the search terms
You can use these strategies in the basic and advanced search boxes in Primo Search and other Library databases.
|Yes* = yes it does this but it works differently. The search techniques accepted by each journal database can vary; if in doubt, check a database's help section.|
