Examples of javax.help.search.SearchEngine

javax.help.search.SearchEngine
Defines the methods used to access a search engine. Each instance is created by a engine factory. Extensions of SearchEngine can perform the search or negotiate the search results with an outside agent. A server search engine is an an example of an outside agent. Search results are returned through SearchEvents to listeners that register with a SearchQuery instance. The SearchQuery is returned from the method createQuery. @author Roger D. Brinkley @version 1.6 03/19/99 @see javax.help.search.SearchEvent @see javax.help.search.SearchListener
