The main search page for a database is called its interface. The appearance of one database interface may look different than that of another; however, an interface generally has the following features:
Search Field: enter keywords or terms that describe a topic.
Boolean Operators: using the terms AND (to combine 2 keywords), OR (search for one keyword or an alternative one), or NOT (find one keyword but exclude another from results) in a search. Databases generally default to AND.
Select a Field: look for a keyword within certain fields, such as author, title, or publication title.
Limiters: narrow a search to find information with certain characteristics, such as being full text only, a peer reviewed journal, or publication type.
Search: the button that executes a database search.
