Once here choose Online Databases. Click on the title of the database to connect. Here search terms can be entered. During a basic search the database search engine will look for the term, or terms entered, in all of the fields in each record within the database. It is here on the advanced search screen that the unique limiters for the database can usually be found.
Limiters allow for control of the types of records the database retrieves.
Limiters vary between databases, therefore each database should be checked for its list of limit features. Some full text databases will allow for searching within the full text of the articles, as opposed to simply searching the citation and abstract. The term Boolean refers to a system of logical thought developed by the mathematician George Boole. These terms, which are used to link search words together in an electronic database, enable the searcher to narrow or broaden their searches, so that the exact information needed is retrieved. The process is known as Boolean Searching, and using Boolean Logic.
