Class MultiWordSuggestOracle

    java.lang.Object
      com.google.gwt.user.client.ui.SuggestOracle
          com.google.gwt.user.client.ui.MultiWordSuggestOracle

    public class MultiWordSuggestOracle

extends SuggestOracle

The default `SuggestOracle`. The default oracle returns potential suggestions based on breaking the query into separate words and looking for matches. It also modifies the returned text to show which prefix matched the query term. The matching is case insensitive. All suggestions are sorted before being passed into a response.

Example Table

All Suggestions | Query string | Matching Suggestions
John Smith, Joe Brown, Jane Doe, Jane Smith, Bob Jones | Jo | John Smith, Joe Brown, Bob Jones
John Smith, Joe Brown, Jane Doe, Jane Smith, Bob Jones | Smith | John Smith, Jane Smith
Georgia, New York, California | g | Georgia
