Whether searching library databases or web search engines, you will usually want to try several, since no database is comprehensive in its coverage. Look for the existence of such a list and use the terms for your topics for searching, but also use the list in brainstorming for search terms, in general. Depending upon the database, this symbol may pull in both singular and plural forms of your term, or, even more often, any additional characters that might appear on that word root in the database. With web search engines, you are often better off, searching on phrases, rather than combining terms with Boolean operators. If so, take advantage of any help the database provides in defining phrases, such as enclosing phrases in quotation marks.
Fuzzy logic establishes links between terms based on their physical proximity in the record.
Online searching is very much of an interactive process. When you retrieve the perfect article or web page, be sure to examine it carefully for clues as to how to bring up similar pages.
