Wildcards
Wildcards allow you to search for alternate spellings of words. By replacing a letter with a question mark, an asterisk or a hash symbol you are quickly able to search for both the American and British versions of search terms. Note that some databases use different symbols as wildcards so check vendor's help pages before using them. The asterisk is the most commonly used option. For example:
analy?e = analyse or anlayze
behavio*r = behaviour or behavior
colo#r = colour or color
synthesi*e = synthesize or synthesise
Truncation
To truncate a word, reduce it to its most basic form or root word. In this example, we are using ‘counsel’. Place an asterisk at the end of the root word to find multiple endings. The database will search for all the variant forms of the word, its tenses, plurals and in some cases alternate spellings. For example:
counsel* = counselling, counseling, counsellor, counselled, counsel and so on.
Phrases
When a phrase is enclosed by double quotation marks, the exact phrase is searched. You can use this when you are looking for a specific title from a reading list or for a particular phrase or term. For example:
“cognitive behaviour therapy”
"type 2 diabetes"
