To use the Search features, select 1 of the 3 options below:
To use the Contains any words feature, enter your keywords into the search box separated by a space. Do not include commas or Boolean operators. The results will contain all publications with any of the keywords within the document title, metadata, or text. Those publications with all keywords will be ranked higher in relevance.
When using the Contains all words feature, the results will include only publications that contain each of the keywords within the document title, metadata, or text.
The advanced search option allows you to search using advanced search syntax. Below is a list of advanced search features you can use and the syntax for each.
Combine keywords using the Boolean operators AND, OR, and NOT. These commands can be paired with parentheses.
Wildcards and Truncation
Use the wildcard symbol (*) to retrieve keywords with multiple word endings.
Example: therap* will retrieve the words therapy, therapies, therapist, therapists, therapeutic, and so on.
Use quotations marks around more than 1 keyword to search for a phrase.
Example: Using quotation marks around “prostate cancer” will retrieve results that have that exact phrase.
To search for keywords that are near to one another, place the keywords in quotations and add a ~n after. Replace n with a number to set the maximum number of words the keywords can be apart. The keywords may appear in any order.
Example: “animal therapy”~3 will retrieve the phrase animal therapy, as well as animal assisted therapy, animal or music therapy, therapy animal, and so on.
