    Help with searching

    Quick Search

    A quick search box is available at the top right of every page. A search returns a list of articles in order of relevance. A Quick Search will search across all Full Text content including Titles, Author, Abstracts, and Keywords.

    Users may then use filters to search within the results, further refine their search, or select content to which they have full-text access.

    Creating Advanced Searches

    The Advanced Search page can be used to build more complex searches and to search specific fields (e.g. Title or Author). In addition, users may use Boolean operators in both the Advanced and Quick Searches.

    Search allows use of Boolean operators (AND/OR/NOT). By default, a search on a string of words will return results containing the individual words, e.g. fibonacci sequence will return the same search results as fibonacci AND sequence.

    To search for an exact phrase, enclose the phrase in quotation marks ("), e.g. "fibonacci sequence" returns only results with these two words together in this order - an exact text match of the phrase.

    Use (*) as a wild card. e.g. math*, will return searches containing math, maths, mathematics, mathematical, etc; while colo*r will return searches containing colour as well as color.

    Basic algorithmic stemming is used to disregard some word endings, e.g. a search for city will automatically include cities.

    Users may then use filters to refine the search further or select content they wish to view.
