Choosing a search type
One way to control your search is to select from among a number of search types.
Basic search is the simplest search; it lets you look for a single word or phrase in a designated area of the text. Because it is less specific, sometimes your search results wil be larger than for advanced searches that let you be more specific in your search query.
Boolean search lets you look for combinations of up to three terms or phrases using Boolean connector terms (i.e., AND, OR, NOT).
