Asterisk *ĭepending on the database or platform, use before (uncommon feature, available in Web of Science and Scopus, for example), within (as a wildcard, depends on database/platform), or at the end of a word root or string (most common option) to replace zero to multiple characters. Please see the database-specific operators and fields for more information. ![]() The asterisk is the most common truncation symbol.ĭepending on the platform you are using to search a given database (e.g., EBSCOhost, Ovid, ProQuest), other truncation and wildcard symbols may be available to use, for example, within words. ![]() Truncation symbols are shortcut characters which can help to include variations of your text word without having to type each variation into the search separately. Parentheses work in most but not all systems (e.g., they work on the Ovid, PubMed, EBSCOhost, ProQuest, Scopus, and Web of Science platforms, but they are ignored in Google and Google Scholar)Į.g., (chest OR thorax OR thoracic) AND (imaging OR radiographs OR radiography) Use parentheses to set the order of execution of the Boolean logic. Please see the database-specific operators and search fields.e.g., on the Ovid platform, adjn is used: primary adj3 care.The operator, if available, is dependent on the database and platform being searched.Many bibliographic databases also allow use of proximity operators.we do not usually recommend that you use NOT in your searches, as you may exclude relevant results. ![]()
